Which DC villain stands above the rest? Choosing an antagonist from Batman’s collection of criminals is understandable. Characters like the Riddler, Joker, Catwoman, and Penguin tend to leave a stronger impression than Superman’s enemies such as Darkseid or Lex Luthor. (And who recalls Metallo?) However, the 2027 Superman follow-up, Man of Tomorrow, may finally give one of Superman’s adversaries the spotlight.

Through unexpected casting, a famous Superman villain from the comics will be truly terrifying. Lars Eidinger has been confirmed to play Brainiac in the 2027 Superman sequel, Man of Tomorrow. But who is this performer? And will this casting finally make Brainiac cool?

Director James Gunn stated that Eidinger was selected following a global search for the perfect actor for the role. Although some cinema enthusiasts may know Eidinger from his performances in All the Light We Cannot See or the newer movie White Noise, he isn’t exactly a mainstream star.

This is precisely what makes the casting decision so intelligent. In theory, Brainiac is a mysterious DC antagonist, yet also a true genius and a physical powerhouse capable of defeating Superman in combat. Therefore, it’s beneficial that Eidinger isn’t a major Hollywood celebrity. This will make it simpler for audiences to embrace him as Brainiac.

What can we anticipate from Gunn’s interpretation of Brainiac? Essentially, as an extraterrestrial android, Brainiac’s main evil act is reducing entire metropolises to microscopic proportions. In traditional Superman mythology, Brainiac is responsible for shrinking Krypton’s city of Kandor, famously known as the “Bottle City of Kandor.”

The ramifications for the new DC Universe could be substantial. If Brainiac introduces a Bottle City of Kandor, we may encounter Kryptonian counterparts to Superman and Supergirl. Given the 2025 Superman film’s events, will we discover that all surviving Kryptonians share a disregard for humanity?

In essence, if Brainiac returns with numerous Kryptonians via a miniaturized city, he may not be the sole antagonist in the film. If so, the unexpected casting of Lars Eidinger could be concealing another unforeseen plot development.

Man of Tomorrow arrives in cinemas on July 9, 2027.
