Ben Affleck made an appearance at Comic-Con, which shocked everyone! No one expected to see him because he recently broke the news of his divorce.  Still he showed up at the Batman v Superman panel, and told an interesting story about meeting Christian Bale in a costume store where he was getting his son a Batman costume. And asked Christian for some advice on playing Batman. Hilariously, Christian said "make sure you can pee in the suit!"

Here is the Comic-Con trailer for Batman v Superman!
