Who else might be in Superman: Legacy?

It's not yet clear which other characters from the comic books might make it into this big-screen adaptation, while it's also not apparent who Gunn was referring to when he said someone who had been cast who is not one of the "regular players in the Superman world."

We can expect a variety of Superman supporting characters including Lex Luthor, Jonathan Kent, Martha Kent, Jimmy Olsen, Perry White, and many more.

One person who does appear to be a reasonable bet for a role is the director's brother Sean Gunn, who has appeared in many of his brother's films including all three Guardians of the Galaxy movies and The Suicide Squad.

Superman: Legacy will be released in cinemas on 11th July 2025. Check out more of our Film coverage or find something to watch now with our TV Guide and Streaming Guide.
