James Gunn confirms Lars Eidinger will play Brainiac in Man of Tomorrow.

Filming for Man of Tomorrow has wrapped, although no release timetable for a first look or trailer has been announced beyond speculation that a trailer may not arrive until 2027.
Milly Alcock is expected to make a cameo as Supergirl, reprising her role as Superman’s Kryptonian cousin from the DCU.
The returning ensemble includes Skyler Gisondo as Jimmy Olsen, Sara Sampaio as Eve Teschmacher and Frank Grillo as Rick Flag Sr., alongside other actors including Andre Royo, Matthew Lillard and Sinqua Walls.
Gunn said he would prefer to reveal neither the new Superman suit nor Brainiac before audiences see the movie, telling fans, “I’d rather show people nothing and have people see everything in theaters,” while acknowledging that a complete lack of promotion is impractical.
James Gunn has confirmed that Lars Eidinger will play Brainiac in the 2027 sequel Man of Tomorrow, with Superman and Lex Luthor forming an uneasy alliance against the villain. The director dismissed much online casting speculation as exaggerated or false, stating he wants to keep major details like Superman's new suit secret until the film's July 9, 2027 release.
David Corenswet, Nicholas Hoult and Rachel Brosnahan are returning to the film, while Adria Arjona's undisclosed role continues fueling speculation about possible DC character appearances. Gunn emphasized the sequel will remain focused on its core characters rather than becoming a cameo-heavy crossover.
Lars Eidinger's casting as Brainiac marks the film's primary antagonist, with the villain driving the central conflict between Superman and Lex Luthor. Gunn confirmed Brainiac will be the focus rather than a supporting player in a crowded ensemble. The director wants audiences to experience the character's full reveal in theaters rather than through advance promotional materials.
Online speculation has run rampant about possible cameos and new character introductions, but Gunn indicated much of this is false. He emphasized that Man of Tomorrow will maintain focus on Superman and Lex's complex relationship. The director acknowledged that keeping promotional materials minimal creates an unusual challenge for marketing a major studio film.
Gunn stated he would prefer to reveal neither Superman's redesigned suit nor Brainiac before release, telling fans: "I'd rather show people nothing and have people see everything in theaters." He acknowledged that complete promotional silence is impractical, meaning some footage will eventually emerge before the July 2027 theatrical debut. A trailer timeline has not been announced, though speculation suggests it may not arrive until 2027.
