James Gunn Addresses Popular Man of Tomorrow Villain Fan Theory

by

Earlier this year, James Gunn surprised DC fans by announcing his next Superman movie, titled *Man of Tomorrow*. Set to release in July 2027, the film will surprisingly pair Superman with his longtime enemy, Lex Luthor, to fight a major new threat. Since the announcement, fans have been guessing who this threat might be, and a leading theory suggests it’s Brainiac, a classic Superman villain. Brainiac is powerful enough to force Superman and Lex to work together, and some noticed the script’s title page includes an image of a brain cut in half, fueling the speculation. Gunn has now responded to the rumors about Brainiac’s involvement.

James Gunn told *Entertainment Weekly* he expected the script cover he shared would get fans speculating. He acknowledged, “I knew posting that cover would start a conversation,” but added that he’s not ready to reveal what it all means just yet.

When Could the Man of Tomorrow Villain Be Confirmed?

Spoilers for Peacemaker Season 2

With almost two years until *Man of Tomorrow* comes out, James Gunn doesn’t need to share many details just yet-especially because he’s currently focused on finishing the last two episodes of *Peacemaker* Season 2. In fact, *Peacemaker* might be the reason he’s being secretive about the villain in *Man of Tomorrow*. Gunn has said the *Peacemaker* finale is crucial to the upcoming film, potentially setting up the antagonist and preserving a big reveal. He’s likely keeping things quiet to avoid spoiling the surprise.

The series *Peacemaker* has already started building the story for the upcoming *Man of Tomorrow* film, thanks to a surprise appearance by Lex Luthor. James Gunn wants each DC movie and show to be enjoyable on its own, so viewers don’t need to watch everything to understand what’s happening. However, these projects will still share a connected universe, meaning stories will overlap. *Peacemaker* was positioned as a continuation of the *Superman* movie, so it makes sense that it’s now connecting that film to *Man of Tomorrow*. As Rick Flag Sr. continues investigating Peacemaker’s portal, his complicated relationship with Lex Luthor will likely be explored more, and these developments will be important for the plot of *Man of Tomorrow*.

If the season finale of *Peacemaker* doesn’t reveal who the *Man of Tomorrow* villain is, fans likely won’t find out until next year when the movie starts filming. Finding the right actor for the role will take time, and James Gunn might announce details as soon as someone is cast to prevent leaks and speculation. Gunn often keeps fans informed about his projects, letting them know what to expect. With rumors sure to spread as filming gets closer, Gunn might want to quickly clarify who the villain is to avoid confusion.

As we learn more about the upcoming film, the meaning behind the brain diagram is becoming increasingly intriguing. While many fans assume it points to Brainiac as the villain, it could represent something else entirely. James Gunn has emphasized that the movie focuses heavily on Lex Luthor, exploring a more sympathetic side of his character. It’s possible Lex sees himself as the “man of tomorrow,” believing his intelligence is the key to saving the world from a major crisis. With the U.S. government relying on his expertise to address a problem involving the multiverse, Lex likely feels he’s the only one who can protect his reality.
