After testing actors over the past couple weeks, Warner Bros. and D.C. have tapped theater actor Ray Fisher for the role of Cyborg in the untitled Batman-Superman pic.
Cyborg, while not a major part in the Batman-Superman feature, is a member of the Justice League and will become a much more significant role as Warner and D.C. develop more films related to the Justice League universe, sources confirm.
