Sharlto Copley V James Franco
Sam Rockwell V Christoph Waltz
Matt Smith V Ben Mendelsohn
Walton Goggins V Michael Emerson
Johnny Depp V Michael C. Hall
Benedict Cumberbatch V Alfie Alan
This next one, in my opinion, is the hardest decision.
Vincent Cassel V Crispin Glover
The two most realistic casting choices for the role, because both of them have already been cast in the movie (Batman V Superman: Dawn of Justice) as characters we do not yet know.
Callan Mulvey V Scoot McNairy
Batman V Superman: Dawn of Justice is in theaters May 6th, 2016.
Thanks for voting! -Sam
