Ben Affleck apparently had some problems with the script for "Batman v Superman: Dawn of Justice," so he did what any leading man who also happened to have an Oscar for screenwriting would do and took matters into his own hands.

While wearing his Batman costume, of course.

Affleck "would go into wardrobe and get all suited up for the day in his Batman suit," a source explained to Us Weekly. "Then he would sit around reworking the script. Ben wasn't thrilled with it and would find himself on multiple occasions fixing it the day of."

Hey, every writer has his or her own process, right?
