The premiere of Craig Gillespie’s DC superhero movie “Supergirl” took place in Brooklyn, New York, last night, Monday, June 22 — and, of course, its star Milly Alcock was in attendance.
Alcock made her debut as the character — also known as Kara Zor-El — in last year’s “Superman” film. She made an uncredited cameo at the movie’s climax, turning up drunk to collect her dog, Krypto, from the Fortress of Solitude, where David Corenswet’s Kal-El was recuperating after the movie’s dramatic events.
With her own film coming out this Friday, June 26, the stars were out in force at the premiere to see it ahead of its release.
26-year-old Australian actress and “House of the Dragon” star Alcock took to social media to post a series of photographs ahead of the event. The pictures include a couple with her boyfriend, Jo Powell.
Milly Alcock & Jo Powell Make a Wonderful Couple
Milly Alcock shared a carousel of four photographs from the premiere of “Supergirl” with her 2.1 million followers on her Instagram account.
The first two pictures show Alcock with her boyfriend, Jo Powell, the head of a London-based food project called “Schoolnights.” The couple had made their red carpet debut earlier this year at the 2026 BAFTA Awards in London, England.
Alcock wore a black Balenciaga top, trousers, and opera gloves. Powell wore a loose-fitting suit and long tie.
In the third picture, Alcock is with “Supergirl” director Craig Gillespie. In the fourth, she is posing alone.
The actress captioned the post, “Supergirl premier ❤️!!!! SuperGirl lands in theatres on June 25th 🤯 Get your tickets now 💕.”
She also tagged several accounts, including the photographer and some of the people involved in creating her look for the event.
Alcock’s fans flocked to the post’s comment section to have their say.
