Hold onto your capes, DC fans, because the rumors about Brainiac in James Gunn’s Man of Tomorrow just got a whole lot more intriguing. But here’s where it gets controversial: despite reports linking actors like Dave Bautista to the iconic Superman villain, Gunn himself has stepped in to set the record straight—sort of. In a recent Threads post, the DC Studios co-CEO addressed the swirling speculation, stating, ‘Let’s forget a moment I’ve never said Brainiac was in the movie.’ Wait, what? That’s right—he didn’t deny it outright, leaving fans in a tantalizing gray area. And this is the part most people miss: while Gunn debunked casting rumors (including Bautista’s), he never explicitly ruled out Brainiac’s presence in the film. So, is this a clever misdirection, or just a storm in a teacup? Let’s break it down.
First, let’s talk about the elephant in the room: Dave Bautista. Back in November 2025, The Wrap reported that Bautista was a frontrunner to play Brainiac, sending fans into a frenzy. Fast forward to now, and Gunn clarifies he and Bautista have never discussed the role. But here’s the kicker—Gunn admits he loves Bautista and has ideas for him in the DC Universe. Could this be a subtle hint, or just a friendly gesture? It’s enough to keep the rumor mill churning. Other names, like Matt Smith, have also been thrown into the mix, though Gunn hasn’t confirmed any discussions.
Now, let’s dive into the clues that suggest Brainiac might still be in play. Remember when Gunn shared the Man of Tomorrow script cover in September 2025? Fans immediately speculated about Brainiac’s involvement. When asked directly, Gunn admitted he knew the post would spark debate but remained tight-lipped. ‘We’ll hold off from what exactly is happening,’ he said, leaving the door wide open for interpretation. Add to that the fact that Superman (David Corenswet) and Lex Luthor (Nicholas Hoult) are teaming up against a ‘much bigger threat,’ and Brainiac fits that bill perfectly. Gunn even described the film as ‘as much a Lex movie as it is a Superman movie,’ hinting at a complex, high-stakes narrative.
Here’s the real question: Is Gunn playing 4D chess with fans, or are we reading too much into his words? While he’s quick to dismiss casting rumors, his refusal to outright deny Brainiac’s involvement feels deliberate. It’s a classic Gunn move—keeping us guessing while building hype. With filming set to begin in 2026 and a July 9, 2027 release date, we won’t have to wait long for answers. But until then, let’s debate: Is Brainiac the villain we’re all expecting, or is Gunn pulling a fast one? Sound off in the comments—we want to hear your take!
