As a movie enthusiast, I can’t help but ponder if there might be a surprise appearance by Supergirl in James Gunn’s upcoming Superman film. The buzz surrounding Milly Alcock’s character, Kara Zor-El, has been steadily growing. With recent whispers of potential fan leaks, it seems we may finally have our answer soon enough!
So, will Supergirl be in James Gunn’s Superman? Here’s everything we know.

Does Supergirl appear in James Gunn’s Superman?
Several reliable sources claim that Milly Alcock is set to make her first appearance as Supergirl in the forthcoming Superman film, according to ComicBookMovie.com.
Before hitting theaters on July 11, Superman had its premiere at the TCL Chinese Theatre on July 7, 2025. Several insiders who have watched the film say that there will be two extra scenes following the credits in Superman.
In the movie’s finale, there are rumors suggesting Supergirl makes an appearance, demanding her pet Krypto back. Her behavior seems intoxicated, and she addresses Superman disrespectfully as a “vulgar term.” This could imply some tension between them. However, it’s important to remember that these leaks originate from unofficial sources, so they should be treated with caution.
In January 2024, Milly Alcock, renowned for her role as a young Rhaenyra Targaryen in HBO’s House of the Dragon, was selected to portray Kara Zor-El in the 2026 DC Universe movie Supergirl. Since this news broke, fans have been speculating that she could also appear in Superman.
In response to a fan’s question about Alcock’s screen time in Superman, director James Gunn playfully replied, “I never mentioned she was in the movie at all.” Despite this, many fans remain convinced that her cameo is still a possibility. The mysterious response from Gunn and rumors leaked by fans hint that it might be feasible to see Alcock wearing the Superman costume this coming Friday.
It’s yet undecided if Alcock will feature in Superman, but she is preparing to broaden the DC Universe with the upcoming Supergirl movie in 2026, which is part of DC’s Chapter One: Gods and Monsters series and is scheduled for release on June 26, 2026.
