The James Gunn Superman casting process for Brainiac is now advancing as the villain has been officially confirmed for Man of Tomorrow, the highly anticipated Superman sequel. Reports indicate casting discussions are underway, generating buzz about which actor could take on the key antagonist role in the film set to connect the new DC Universe storyline.
Brainiac Confirmed as Main Villain in Man of Tomorrow
After months of rumors, Brainiac will finally be brought to the screen as Superman’s adversary in Man of Tomorrow. James Gunn, who is directing the film, first sparked discussion when he posted the script’s cover image, hinting at Brainiac’s involvement. Gunn said,
Listen, of course I wasn’t unaware that when I posted the cover of the script that there was going to be discussion around that particular topic. But I think we’ll hold off from what exactly is happening.
This statement acknowledged the growing excitement while maintaining secrecy around plot specifics.
Actors Under Consideration for Brainiac Role
The search for the perfect Brainiac has led Gunn to meet with several promising actors. According to insider Grace Randolph, David Hyde Pierce, known for his performances in Frasier, Wallace Shawn from Young Sheldon, and Claes Bang, who starred in Dracula, are among those being considered. Shortly after, @ApocHorseman of Nexus Point News confirmed Bang’s candidacy, stating,
I can confirm I heard Claes Bang too. But there’s a handful of others who are going to be tested, so it’s undecided.
Bang is recognized for his chilling work in Bad Sisters, suggesting he could bring a serious and intellectual dimension to the villain’s character.

Gunn’s Unique Approach to DC Universe Casting
James Gunn continues to favor skilled performers over headline star power in assembling his cast, prioritizing match and talent above celebrity status. His choices have led to speculation that this strategy is about both keeping production budgets manageable and finding actors who best fit the roles. This has become a trend in Gunn’s creative process, contributing to heightened anticipation for an official casting announcement, which may arrive before year’s end.
Man of Tomorrow and Its Place in the DCU
Gunn remains open about the interconnected nature of his DC Universe, and Man of Tomorrow will blend seamlessly with ongoing stories. He explained,
Everything’s connected, so there is a story here that we’re telling throughout the DCU, and this is connected very much to Man of Tomorrow. But there are other elements, and part of that is the relationship between Rick Flag and Lex Luthor, and that’s an important thing going forward in the DCU and Man of Tomorrow and so on.
This comment reveals that the film’s narrative will also develop key figures like Rick Flag and Lex Luthor, further weaving together the universe’s storylines.
Gunn expanded on this, adding,
It’s more complicated than that, but that’s a big part of it. It’s as much a Lex movie as it is a Superman movie. I loved working with Nicholas Hoult. I relate to the character of Lex, sadly. I really wanted to create something extraordinary with the two of them. I just love the script so much.
This insight shows his enthusiasm for developing both Superman and Lex Luthor, with Nicholas Hoult cast as Lex, ensuring their on-screen dynamic is a central element.
Anticipation Builds Ahead of Release
Excitement surrounding Man of Tomorrow continues to grow, with fans speculating about the final James Gunn Superman casting choices for Brainiac. The film remains scheduled for a July 9, 2027 release in theaters, promising a major chapter in the evolving DCU narrative, significant roles for both Superman and Lex Luthor, and a new live-action Brainiac poised to challenge the Man of Steel.
