The potential Justice League roster just expanded by one in Zack Snyder‘s new vision of the DC Universe. Theater actor Ray Fisher (not the football player) has been cast as Cyborg in Batman vs. Superman. Since Fisher just played Muhammed Ali in a play staged in New York, he should have the chops to sign on as Cyborg.

Variety reports that the character won’t have a large role in the film, but his role could expand as Warner Bros. preps more DC Universe films. That raises more questions than it answers, really. Variety says “[Cyborg] will become a much more significant role as Warner and D.C. develop more films related to the Justice League universe, sources confirm.”

Cyborg is more closely associated with the Teen Titans, but has been part of Justice League stories as well. Clearly that’s the angle Snyder & Co. are relying upon for the film. (Though a Teen Titans movie might seem like a smart move down the road for DC and WB, it doesn’t seem like a likely choice at the moment.)

Cyborg is also associated with S.T.A.R. Labs, which got a brief mention in Man of Steel. Last year, David Goyer explicitly mentioned that adding nods to S.T.A.R. Labs was meant to tie Cyborg to the film: “We mentioned S.T.A.R. Labs at one point, that’s kind of a connection to Cyborg.”

Fisher was among the young actors who tested for a prominent role in Star Wars Episode VII. Presumably this means he won’t be in that film. Below is a shot of the actor as Ali.

The new Batman/Superman movie is in production now, with a cast that also includes Henry Cavill as Superman, Ben Affleck as Bruce Wayne/Batman, Jesse Eisenberg as Lex Luthor, Gal Gadot as Wonder Woman, and Amy Adams as Lois Lane. Zack Snyder is directing from a script by David Goyer from a story by Goyer and Snyder.

Batman vs. Superman is still a working title. Variety references the film as the “untitled Batman-Superman feature.” Whatever the film ends up being called, it is currently scheduled for release on May 6, 2016.
