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.

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'.

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.
