But before he put on the iconic cape and cowl to film "Batman v Superman: Dawn of Justice," his predecessor, Christian Bale, offered him some advice.
His first tip: beware bathroom breaks.
"Be able to take a piss by yourself," he said, according to the NY Daily News. "I found it to be ridiculously unheroic between takes when I said, 'Excuse me, I need to pee, could somebody undo me please?' "
His second tip: that mask is really heavy.
"I took three people 20 minutes with tools in order to take that cowl off (my) head," says Bale.
Bale also recently admitted his initial reaction to Affleck being cast was jealousy.
Remember how crappy 2003's Daredevil was? Ben Affleck does, and he wants you to know, when he plays Batman, it won't be as bad. In an interview with NPR on his new film Gone Girl, Affleck had this to say about playing The Caped Crusader:
Indeed I have regrets about Daredevil. I have regrets about all the movies that I don't think were executed properly. ... Look, if I thought we were remaking Daredevil, I'd be out there picketing myself ... and that goes for other movies as well that I haven't been happy with. You know, I'm hard on myself and I have exacting standards and I want to do excellent work and I don't always succeed, but I think you have to start out with that drive.
[Batman] was written by Chris Terrio, who wrote Argo, who's not a comic guy. And it's directed by Zach Snyder, who's a incredibly magical sort of visual stylist who's steeped in the comic world. And you have this sandwich of talents. I felt very confident about it. ... I thought it would be nice to make one of these movies really, really good.
