I'm probably not alone in completely forgetting that Ben Affleck played Superman actor George Reeves in Hollywoodland.
Thanks to that film though we now have this inspired trailer mashup from Youtube user Todd Spence, taking Batman V Superman: Dawn of Justice Affleck and putting him up against Old School Superman Affleck. It's like watching Face/Off if they both had the same face at the same time, and without the John Woo doves.
The only thing weirder would be if both of these Affleck's faced their counterpart Daredevil Affleck in a triple threat fight.
