Surprisingly, ahead of James Gunn, we get a first look at Milly Alcock in the Supergirl costume thanks to set images and video that have leaked online out of London, which tease that some sort of big battle is about to take place.
From the same YouTuber that gave us that leaked Avengers: Doomsday battle video, check out Milly Alcock as Supergirl in action from the upcoming DCU movie.
What is happening?
The set images and video come from drone footage revealing a look at the action. It’s actually not clear if that is Milly Alcock or her stunt double, but at least it gives us an idea of the Supergirl costume, which looks to be comic book accurate.

According to the account, Milly Alock is standing on top of some sort of what looks to be a military vehicle of some kind. It’s said she is about to do battle with who could be the villain of the film, Krem of the Yellow Hills, played by Matthias Schoenaerts. It could also be very well possible that Supergirl is about to throw down with Jason Momoa’s Lobo.

It’s known the plot of the film is set out in space, so this scene looks to be a part of an alien planet.

Release info
Supergirl gets released on June 26, 2026, directed by Craig Gillespie, with the script by Ana Nogueira.
“We see the difference between Superman who was sent to Earth and raised by loving parents from the time he was an infant, versus Supergirl who was raised on a rock, a chip off Krypton, and watched everyone around her die and be killed in terrible ways for the first 14 years of her life, and then came to Earth when she was a young girl,” said Gunn at the press event from January 2023. “She’s much more hardcore, she’s not exactly the Supergirl we’re used to seeing.”
