Before flying into the DC Universe as Kara Zor-El, Milly Alcock accidentally became one of the Golden Globes’ most unexpected viral stars. A brief giggle fit during the prestigious awards ceremony left the internet convinced that something hilarious had unfolded off-camera. Now, years later, the actress has finally pulled back the curtain on the unforgettable moment, revealing that the real story was far more chaotic than anyone imagined.

Here’s what the Supergirl star revealed about what actually happened behind her viral Golden Globes laugh.

Recently, during an appearance on Royal Court, Milly Alcock recalled attending the star-studded ceremony at just 21, admitting the entire night felt “like a different planet.” Things only spiraled when she unexpectedly had to walk on stage after a few drinks, suddenly finding herself surrounded by Margot Robbie, Quentin Tarantino, Rihanna, and a room full of Hollywood’s biggest names, admitting the surreal experience simply overwhelmed her.

"I've never gone to any sort of like event like this in my entire life. I get there, and I'm like, oh, this is fucking ridiculous. Like, this is crazy. Like, there are all these people that I really admire, and there's like their publicist running around (0:25), and I'm like, this feels like a different planet," Alcock told the Royal Court.

Before becoming the DCU’s new Supergirl, Alcock quietly built one of the industry’s most impressive resumes. She shot to global fame as young Rhaenyra Targaryen in House of the Dragon, later headlined Netflix’s Sirens, and earned widespread praise for her breakout lead role in Upright. Her journey also included acclaimed performances in The Gloaming, Reckoning, Les Norton, and Pine Gap, steadily paving the way for the role that would eventually make her DC’s newest Girl of Steel.

And now, after months of anticipation, Milly Alcock’s first chapter as the DCU’s Supergirl appears to be writing a very different story with audiences, even as critics remain deeply divided over the film.

Supergirl officially arrived in theaters on June 26, 2026, adapting Tom King’s acclaimed Supergirl: Woman of Tomorrow into a gritty space-western adventure. The story follows a battle-hardened Kara Zor-El, who spent her childhood watching Krypton perish before joining the young alien Ruthye on a galaxy-spanning quest to hunt down the ruthless Krem after he poisons Krypto the Superdog. 

Alongside Milly Alcock, the film stars Eve Ridley, Matthias Schoenaerts, Jason Momoa as Lobo, and David Corenswet as Superman. While critics praised Alcock’s performance, many criticized the film’s uneven narrative and visual effects, resulting in a mixed critical reception. Audiences, however, have responded far more warmly, helping Supergirl earn a 76% Rotten Tomatoes Popcornmeter, with many praising its emotional storytelling, expansive cosmic world-building, high-stakes action, and Alcock’s fierce, punk-inspired portrayal of Kara Zor-El.

And while Milly Alcock’s viral Golden Globes moment continues to make headlines, it’s her performance as Kara Zor-El that now seems to be writing the next chapter of her career.
