After testing actors over the past couple of weeks, Warner Bros. and DC have tapped theater actor Ray Fisher for the role of Cyborg in the untitled Batman-Superman pic.

Victor Stone or Cyborg, while not a major part in the Batman-Superman feature, is a member of the Justice League, and the role will become much more significant role as Warner and DC develop more films related to the Justice League universe, sources confirm.

Warner Bros. had no comment on this story.

Fisher joins the Batman-Superman cast that includes Henry Cavill, Ben Affleck, Jesse Eisenberg, Gal Gadot and Amy Adams.

Zack Snyder is directing from a script by David S. Goyer, based on a story by Goyer and Snyder. Production is currently under way in Michigan.

In the bonus feature on the recent “Man of Steel” homevideo release, Cavill, who plays Superman in the film, said there’s a great deal of promise in Cyborg as well as the fictional research facility S.T.A.R. Labs, which appears in several DC Comics.

“I think he would create an incredible bridge between superheroes and humanity,” Cavill said of the Cyborg character.

S.T.A.R. Labs was also the workplace of Justice League characters Professor Hamilton (played by Richard Schiff in “Man of Steel”) and the superhero Rampage, although it’s unclear whether the latter is involved in the Batman-Superman film.

Produced by Charles Roven and Deborah Snyder, the untitled Batman-Superman feature opens May 6, 2016.

Fisher, repped by ICM Partners, is more known for his theater roles including the Broadway play “Fetch Clay, Make Man,” in which he portrayed Muhammad Ali.

He was also one of the actors testing for J.J. Abrams’ upcoming “Star Wars: Episode VII.”
