“Game of Thrones” actor Jason Momoa is in talks for a part in Warner Bros.’ untitled Batman-Superman movie, a source close to the project tells Variety.

The source did not know what character Momoa would be playing in the Zack Snyder-directed tentpole, but rumors suggest the role is DC Comics supervillain Doomsday.

Warner Bros. declined to comment on the story.

If a deal closes, Momoa would join Ben Affleck, Henry Cavill and newly minted Wonder Woman Gal Gadot.

Plot details are unknown at this time.

The APA-repped Momoa is best known for his roles in HBO’s “Game of Thrones” and Lionsgate’s “Conan” reboot.

The Hollywood Reporter first reported the news.
