Affleck played Daredevil 20 years ago. Then Affleck played Batman. Now, Pattinson is playing Batman. Affleck could play some fallen villain that Pattinson has to fight, and it would work in the "crossover" universe".
@dave Oh, I got that, I just don't find these crossovers so entertaining as a concept... Well, except for the concept of Tony Stark and Steven Strange investigating a murder, while using a qote "No shit Sherlock"
