Explore the behind-the-scenes stories of James Gunn's 'Superman', including the creative clash with David Corenswet over the film's climax. Discover insights from their discussions and the new documentary detailing the filmmaking process.

"I love David," says Gunn. "One of my favorite actors I've ever worked with. He is wonderful. He also questions everything."

Edited together as part of a 60-minute making-of feature, the seven-minute video shows Gunn walking Corenswet through Superman’s big final confrontation with Nicholas Hoult’s Lex Luthor, and specifically the moment when the Man Of Steel reminds Luthor he’s just as human as the rest of us.
