James Gunn spoke about how the personalities of Superman and Batman influence their suits during an interaction with David Corenswet in the behind-the-scenes documentary, Adventures in the Making of Superman.

Director James Gunn took thoughtful measures to make sure that his Superman movie was bright and colorful, and his leading man was a person who civilians could look to as a kind hero that they would want to be friends with.

A letter to Warner Bros. Discovery shareholders on Thursday said that 'Superman' director Gunn is working on 'Supergirl: Woman of Tomorrow,' 'Clayface', and the next 'Wonder Woman'.
