"I'm not very good at my job." — Milly Alcock, The Tonight Show with Jimmy Fallon, 2025
At thirteen, Milly Alcock picked up the phone and called an agency in Sydney. She asked for an audition. No one had suggested it. No one had taken her. She had just learned something she would later say in every version of the same sentence: no one was going to do it for her. So she did it.
Nine years later, she was washing dishes in a Petersham restaurant and living back at her mum's place. HBO sent her a self-tape for an unnamed project (the names in the script had been blacked out). A friend recognized the scene. A Game of Thrones scene. Arya Stark. Milly had never watched Game of Thrones. She filmed the tape anyway.
Six months later she landed as Princess Rhaenyra Targaryen, heir to an iron throne.
On day two of filming, someone very high up at HBO pulled her aside. "We're gonna get you an acting coach."
Years later, on her first ever American talk show, Milly told that story to Jimmy Fallon and delivered the epigraph of this piece as a punchline. The audience laughed. It landed as humility. It was actually a thesis.
Two performances. One person. The thirteen-year-old cold-calling agents. The twenty-five-year-old telling a network television host she's an imposter. Both of them are her. That is the door she keeps opening and flinching through.
TL;DR: Why Milly Alcock is an Enneagram Type 6
Type 6w7, The Loyalist. Core fear: being unsupported and unsafe. Core desire: security. Wing 7 adds the humor, the social warmth, and the chilli-oil-on-ice-cream permission to be weird.
Counter-phobic action, phobic collapse. She builds her own door at 13. She freezes at 22 when the door actually opens.
Tell-on-yourself as defense. She disarms every interviewer by being the first to doubt herself out loud. The self-deprecation reads as humility. It is actually a perimeter.
Loyalty is her currency. Emily Carey. Paddy Considine. Rhys Ifans. Meghann Fahy. She doesn't light up for the role. She lights up for the people in it with her.
Under the cape: the same attic kid. Supergirl is the biggest franchise test a Six could fail. Her strategy for surviving it is not becoming anyone new.
What is Milly Alcock's personality type?
Milly Alcock is an Enneagram Type 6
Type 6 lives in the space between action and doubt. They act, then second-guess. They trust, then verify. They commit, then scan for the exit. The engine that drives them is a single question running in the background of every interaction: Is the ground under me actually solid, or am I about to fall?
Milly Alcock answers that question out loud, in real time, in front of cameras.
When HBO said "we're getting you an acting coach," a Type 3 would have argued. A Type 8 would have dared them to fire her. A Type 6 heard the words and thought, they finally noticed. That's the Six's private architecture: a permanent file labeled "proof I don't belong here," always open, always accepting new evidence.
But Sixes also act. Fiercely. Early. Before anyone helps them. The thirteen-year-old phone call isn't a story about precocity. It's a story about a kid who had already calculated that no rescue was coming. What she told Vogue Australia about that call (below) isn't a motivational slogan. It's a risk assessment.
Riso and Hudson describe Sixes as having "both phobic and counter-phobic" impulses: the urge to seek authority and the urge to defy it, sometimes in the same afternoon. Milly enrolled herself in Sydney's Newtown High School of the Performing Arts and told her mum afterward. She dropped out of school entirely when Upright came calling, saying it "was never really my thing." Then she flew to London during the pandemic, alone, and described herself in that moment as "terrified." Both halves of the Six engine, same week.
"I enrolled myself into high school and told my mum when the audition was. I called up my agent when I was 13, because I learned very young that no one's going to do it for me."
— Milly Alcock, Vogue Australia
The wing call is Six with a Seven wing. The 7 wing gives her the giggles onstage at the Golden Globes, the chilli oil on ice cream, the obsession with the Australian punk band Amyl and the Sniffers that her co-stars Paddy Considine and Rhys Ifans kept feeding her. 6w7s are the warmer, funnier, more outwardly social Sixes. They use humor to outrun the doubt. Milly tells on herself before anyone else can, and she makes it a bit. That is the 7 wing doing the job the 6 cannot.
Milly Alcock's childhood in a rugby union household
Most child actors are produced. A parent with a dream, a coach, a manager, a drive to Los Angeles. Milly Alcock produced herself.
She grew up in Petersham, a quiet suburb in Sydney's Inner West. Her mother studied economics and works as a commercial director. Her father and two brothers played rugby. She was the only one in the house who wanted to make up stories for a living. "I think I got my interest in acting because everybody was uninterested in acting," she told Vogue Australia. "I grew up in a predominantly rugby union household; it doesn't make any sense."
The family didn't model acting. They didn't encourage it or discourage it; they just lived a different life. Milly's early acting career wasn't a rebellion against her family. It was a rebellion against the drift of nothing happening.
So at six she wore a denim skirt and cowboy boots in her church theatre's Little Red Rocking Hood. At thirteen she phoned that Sydney agency on her own landline. By the time she was fifteen, she had enrolled herself in Newtown High School of the Performing Arts and informed her mother of the audition date.
Source: Flaunt Magazine, August 2022 — "Go Ahead, Unleash That Voice." Alcock describes rewinding a stolen Blockbuster DVD of Breakfast at Tiffany's obsessively as a child. Later, on the Sirens press tour, she names Annie and Matilda as the films that made her want to act.
Notice the pattern in the movies she fixated on. Breakfast at Tiffany's, a woman performing a self she invented. Annie, a kid nobody came to rescue, rescuing herself. Matilda, a brilliant child in a house that doesn't understand her, finding her own power. Three films about girls who had to cast themselves before anyone else would. Milly didn't memorize Annie by accident. She was reading the instruction manual.
The bridge from school plays to HBO was a small Australian comedy almost no American reader has heard of. Upright, created by Tim Minchin for Sky and Foxtel, cast her as Meg Adams, a foul-mouthed runaway teenager who literally crashes her car into Lucky Flynn's life and ends up shotgunning an upright piano across the Outback toward his dying mother. The show ran two seasons. She dropped out of school to do it ("Education was never really my thing"). The role required her to hold the screen opposite a 45-year-old composer-comedian for hour-long episodes. It's the proof reel that got her the redacted Rhaenyra tape. Without Upright, no Targaryen. Without Tim Minchin's piano, no Iron Throne.
The wound under all of this, if you want to call it one, isn't abandonment but under-resourcing. The quiet realization that if her life was going to shape itself around acting, she was the only one with the blueprints.
Love without logistics. That is the kind of childhood that produces a thirteen-year-old who calls the agent herself. It is also the kind that produces a twenty-two-year-old who keeps checking whether she is still allowed to be in the room.
Then she got what she wanted.

She had been washing dishes in a Petersham restaurant when HBO's redacted tape landed. She shot it on a phone. When the call came, she told Stellar magazine, "I was washing dishes in a restaurant, living in my mum's attic. This doesn't happen to people like me."
People like me. She grouped herself with the ordinary. She pre-emptively cast herself out of the category of people to whom life hands a Targaryen role. When the door opened, she walked through thinking there has been a mistake.
So when, on day two of filming, a senior HBO executive pulled her aside and told her she was getting an acting coach, the universe confirmed what her private file had always predicted.
Of course. They know. They finally figured it out. I told you.
Here is the Type 6 move that almost nobody gets on camera: she did not quit. She did not spiral. She took the coach. She did the work.
What she did with that work is the part fans rarely hear about. To build Rhaenyra, she went back to the tapes. Not the Game of Thrones tapes; wrong actress, wrong dragon. She went back to Cate Blanchett in Elizabeth: The Golden Age and Audrey Hepburn in Roman Holiday. "If you could combine those two women together, I think that is Rhaenyra," she told the press. "She's witty and cheeky, but she has to perform constantly and live up to that regal role. But, you can see under the surface, she's quite uncomfortable in her skin."
Read that last line twice. Quite uncomfortable in her skin. The princess she chose to build was an avatar of the actress who was building her. She didn't borrow Blanchett's regal posture because the role demanded it. She borrowed it because she needed scaffolding for her own discomfort, and a Six knows that the only way to stop being seen as fragile is to perform a borrowed kind of solidity well enough to convince yourself first.
Then there was the language. House Targaryen speaks High Valyrian, a constructed tongue with its own grammar that exists for no purpose except to make actors' jobs harder. Alcock met it the way a Six meets anything she doesn't yet trust herself with: through repetition, supervised. "We just repeated and repeated and repeated until I didn't have to think about what I was saying," she said. The dialect coach wasn't a humiliation. It was a railing.
The other thing she didn't do was meet her replacement. Director Miguel Sapochnik told both Alcock and Emma D'Arcy not to study each other, not to compare notes, not to mirror mannerisms. "Just trust that you both have it." Alcock didn't push back. She trusted the man with the job title and built her Rhaenyra without ever speaking to the older one. Two performers, one character, separated by a directorial fiat, and she held the line. That's loyalty by following protocol, which is loyalty in its purest Six form.
What she did instead was attach to the people in the room with her. Paddy Considine, who played her father King Viserys, and Rhys Ifans, who played her future-father-in-law Otto Hightower, became something between scene partners and chaperones, an English knight and a Welsh actor turning into the household she didn't have on set. They're the ones who fed her the Australian punk band Amyl and the Sniffers, kept her laughing between takes, and gave her a recurring older-male presence to play her princess against. When House of the Dragon Season 2 brought Considine back for a brief flashback opposite her returning Rhaenyra, the choice tracked: of all the relationships in that show, hers with Considine was the one fans had felt the most.
The work paid off. The show won a Golden Globe. At the ceremony, caught off-guard because they had been told the audio cue was a placeholder, she stood up mid-champagne and got the giggles. "I didn't think we were gonna win," she told Fallon. "No one told me that I had to get up. Why would I get up?"
Then the whole internet watched her stand next to Rihanna and laugh helplessly at the fact that she was standing next to Rihanna. Anxiety in Sixes does not always look anxious. Sometimes it looks like giggling on the Golden Globes stage because your brain has decided this cannot possibly be your life.
Why Milly Alcock thought her life was over at 22
Most people hear "I was so shit-scared that my life was over at 22" and assume hyperbole. With Alcock, it was a diagnosis.
House of the Dragon ended. She was replaced in Season 2 by Emma D'Arcy, the older-version actor, a handoff written into her contract from day one. The character she had spent months learning to inhabit simply continued without her. She wasn't in the edit. She wasn't in the marketing.
What a Six loses in that moment is not a role. It is the structure that made the ground feel solid. Rhaenyra had been the thing that said you are allowed to be here. Rhaenyra left. Alcock's version of that loss, told later to Vanity Fair, sounded like the inside of a sleepless night: maybe that was it. Maybe twenty-two was the peak.
Then two things happened in fast succession. Netflix offered her the lead in a five-episode limited series. James Gunn offered her a cape.
She took both. The order matters.
The Sirens detour
Before the cape, she did Simone DeWitt.
Sirens, Netflix's May 2025 dark-comedy adaptation of Molly Smith Metzler's play, dropped Alcock onto a coastal estate opposite Julianne Moore and Meghann Fahy. Simone is the younger sister who hit the lottery: a personal assistant to Moore's billionaire socialite, sharp, ambitious, in love with the proximity to wealth and quietly terrified of being sent back to the life she came from. The character is, by design, the photographic negative of Rhaenyra. The princess inherited her status and couldn't get comfortable in it. Simone clawed her way into someone else's status and would burn the world down to keep her keycard.
This is the Six hedge in casting form. After losing the franchise that defined her, Alcock didn't chase another franchise. She chased a five-episode character study with two of the better living American actresses, on a streamer, with a director willing to let her play someone smaller and meaner. Sixes don't bet everything on one tower. They build a second tower they can run to if the first one falls. Sirens is the second tower.
It also gave her something Rhaenyra never could. Reviews were genuinely warm. Rotten Tomatoes' critics consensus singled out "Julianne Moore, Meghann Fahy, and Milly Alcock" by name. The Hollywood Reporter let her and Fahy walk through the finale on their own terms. For a Six who had spent two years convinced the Targaryen audience would forget her, Sirens was a small empirical disconfirmation: people followed her into a different show.
Her co-star Meghann Fahy, asked on the press tour what she thought of working with Alcock, gave the kind of answer you only get from someone being honest: "You're a great hang. You're a cool girl… I adore you, dude." It was casual. It also named the thing that matters most to a Six: being a great hang, being a person who can be trusted in the room. That praise lands harder for her than any review. It's the language of belonging.
The same perimeter she runs around her work runs around her life. She kept her relationship with chef Jo Powell almost entirely off the record until the 2026 BAFTAs, when she walked the carpet with him for the first time. Her Instagram is sparse and occasional. She doesn't stage her dating life or feed it. The boundary isn't coldness; it's the same engine that makes her tell on herself in interviews. Both moves serve one purpose: control the angle of attack before someone else picks it.
How Milly Alcock handles the Supergirl backlash
The cape was the harder bet.
Supergirl isn't a role in the normal sense. It's a franchise. It's millions of people building an image of who she is, most of whom have never heard her speak, all of whom will have an opinion. For a Six, that's the exact nightmare: an authority built around you, about you, without your consent.
She did what she has done for every job since the agency call at thirteen: she pre-empted the verdict.
She did the interviews before the film came out. She told Vanity Fair she was "utterly terrified." She told the Hollywood Reporter she expected backlash. When a Deadline reporter brought up Martin Scorsese's and Ridley Scott's old, generic broadsides against the superhero genre (comments aimed at Marvel years before her Supergirl existed), she didn't flinch and she didn't posture. "I get it. They've been around for fucking ever making phenomenal films. Not every film is for everyone. The beauty of art is that you can be selective."
Notice what she didn't do. She didn't defend the genre. She didn't argue. She didn't perform excitement. She conceded the critics' best point, then held her small piece of ground. You're right, and also I'm going to keep doing my thing. She gave two Oscar legends the terrain they were asking for and kept the door to her own work open.
There is also the simple physical fact of the role. Supergirl is American. Alcock is from Sydney. She has spent years training her voice into a flat Midwestern accent, the same dialect-coach repetition that built Rhaenyra's English vowels, now being run in reverse. Casting directors had been telling her for years that an American accent would help her land more parts. Now, on the biggest stage available, she is doing it in a cape, and any seam in the dialect will be screen-grabbed and turned into a TikTok before the credits roll. She isn't facing that exposure with bravado. She's facing it by repeating the line in a coach's office until she stops hearing herself.
The Vanity Fair quote captures the same engine: "Of course I'm scared. Of course I want people to like me and the movie. But ultimately, it's out of my control." She names the fear. She names the desire. Then she names the only Six-shaped solution: control what you can, trust what you have to.
"It definitely made me aware that simply existing as a woman in that space is something that people comment on. We have become very comfortable having this weird ownership of women's bodies. I can't really stop them. I can only be myself."
— Milly Alcock to Vanity Fair, 2026
The phone call she keeps making
The thirteen-year-old who called her own agent is still on the line.
The most recent version of that call went to Craig Gillespie. She had just been cast as Supergirl. She did not have notes on the script. She did not have demands about her trailer. She had one sentence she needed to say to the man who was about to direct her in a cape, and she said it before he could form an opinion about her: "I don't know how to be that person. I'm just me."
For a Six, that is the whole architecture in one phone call. Concede the doubt. Name the limitation. Hand the authority figure the worst-case version of you before he gets a chance to discover it on his own. The director can now only be pleasantly surprised. The Six has built a floor under the worst possible review and can walk forward without checking it again. The audience hears humility. The Six hears safety.
When she can't reach the voice on the other end of the line, on the Golden Globes stage, in front of Rihanna, inside a Supergirl suit that still feels borrowed, she falls back to the one-line confession she opens every interview with. I'm not very good at my job. The audience laughs. The anxiety has a container. She gets through the night.
There's a version of Milly Alcock's career where the next phase goes fine. The movie lands, the backlash is survivable, the work gets easier. There's another version where it doesn't, and she has to do what she has been training for since she was thirteen: cast herself again, from scratch, with no one in the room willing to do it for her. Either way, she has practiced the line.
The Targaryen heir, the billionaire's assistant, the Kryptonian, the Golden Globe winner: all of them are the same person, and none of them are the person she thinks she's supposed to become. She'll keep being the kid who picked up the phone, terrified, and dialed anyway.
Back in Petersham, in the attic room with the low ceilings and the single window, the film posters are still on the wall.
