While it is near impossible to tell, director Zack Snyder had a small cameo in Batman v Superman. And we do mean small.
BvS cinematographer Larry Fong revealed on Twitter that Snyder’s hands briefly doubled as Bruce Wayne quick scene. Or at least one part of Bruce Wayne.

During a montage sequence of Bruce Wayne researching Superman, Snyder’s hands doubling as Wayne’s grabbing a cell phone. With Snyder currently still making Justice League, perhaps he can continue doing hand cameos for Batman or perhaps even the Flash or Superman.
