Sam Rockwell has emerged as a leading contender on the reported shortlist to play Brainiac in the upcoming film Man of Tomorrow, according to recent movie news sources. The Sam Rockwell Brainiac shortlist is generating buzz as DC Studios gears up to introduce the powerful adversary to the big screen for the first time, with the film slated for release in 2027.
Speculation Over Brainiac’s Casting Intensifies
The Wrap confirmed last month that Brainiac will debut in Man of Tomorrow, although DC Studios and director James Gunn have yet to make an official announcement. Recently, Nexus Point News reported that Claes Bang, Matt Smith, and Sam Rockwell are the names being considered to portray the technologically advanced villain. This development adds intrigue around Gunn’s highly anticipated follow-up to Superman: Legacy as fans await more concrete updates from the studio.
Shortlist Reveals a Range of Potential Choices
Nexus Point News, which has gained a reputation for reliable comic book movie and TV news, clarified that no offers have been extended to any actors at this stage. They also highlighted,
“budget restrictions at DC Studios may prevent certain desirable names to be cast.”

The actors speculated for the role bring distinct backgrounds to the table. Claes Bang is known for his performances in Dracula and The Northman and was rumored previously for the part. Matt Smith, recognized from Morbius and House of the Dragon, has been a frequent fan-favorite choice. Meanwhile, Sam Rockwell — with credits like Iron Man 2 and The White Lotus — represents a more unexpected direction for the casting, yet social media feedback appears positive regarding his inclusion on the shortlist.
Hints from James Gunn and Ongoing Production Plans
Many observers suspected Brainiac would serve as the primary antagonist in the film after James Gunn shared a script image featuring what appeared to be a medical X-ray with an exposed brain, igniting speculation. Nexus Point News further reported details from the reported casting breakdown:
“Makeup and prosthetics will be used for the film’s antagonist. In addition, actors with a strong build and stature are being looked at for the role.”

James Gunn, when questioned about the script tease, responded,
“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,”
– James Gunn, Director. This comment suggests Gunn is aware of the interest but is withholding further details about Brainiac’s introduction until a later time.
Brainiac’s Cinematic Debut and Connections to Peacemaker
Although Brainiac has previously appeared in series like Smallville and Krypton, his role in Man of Tomorrow will mark the character’s first big-screen outing. The way Brainiac will enter the franchise remains under wraps, but some speculate that events from the Peacemaker season 2 finale could serve as a narrative bridge.
The film is scheduled for theatrical release on July 9, 2027, and production is expected to begin next summer. The official release date was reiterated by James Gunn:

The Ensemble Cast and What to Expect Next
Man of Tomorrow will feature David Corenswet as the Man of Steel, with Nicholas Hoult portraying Lex Luthor. Rachel Brosnahan is set to return as Lois Lane, and Frank Grillo will appear as Rick Flag Sr. Reports also suggest that additional characters from Peacemaker season 2 are likely to participate in the movie, bridging connections across the DC universe.
As anticipation grows around the Sam Rockwell Brainiac shortlist, fans and observers await official casting announcements. The film looks set to expand the scope of DC’s cinematic narratives, introducing formidable new adversaries and potentially weaving ongoing television events into the story’s fabric. With production commencing in the upcoming year, more details should surface as development continues.
