The DC Studios co-chair, who is also writing and directing "Superman: Legacy " for July 2025, tweeted about the casting Tuesday, which a representative from Warner Bros. also confirmed.
The 29-year-old Philadelphia native starred in Ryan Murphy's Netflix series "The Politician" and "Hollywood," as an aspiring actor, and more recently played a theater owner who gets mixed up with Mia Goth's aspiring actress in Ti West's "Pearl."
Their ambitious 10-year plan kicks off with "Superman: Legacy," which Gunn said deals with the superhero's journey to make sense of both his aristocratic Kryptonian heritage and his small town, midwestern upbringing as Clark Kent.
