Many were surprised when Ben Affleck signed on to play the iconic hero Batman in Warner Bros.' Batman v Superman: Dawn of Justice. Some thought he was too old for the role, while others just couldn't see him portraying Bruce Wayne. Others were surprised because he has recently focused on his work behind the camera, with the news of his Batman casting coming just months after he won the Best Picture Oscar for Argo. According to a new report from US Weekly, the actor/filmmaker wasn't "thrilled" with the script and he often performed rewrites on set, in his Batman suit.

"(He) would go into wardrobe and get all suited up for the day in his Batman suit. 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."

Batman v Superman: Dawn of Justice reunited Ben Affleck with his Oscar-winning Argo screenwriter Chris Terrio, although this is the first time we're hearing that the actor wasn't "thrilled" with the script. Naturally, we don't know what changes the actor made to the screenplay, or how extensive the changes were from the shooting script. Ben Affleck also has a screenwriting Oscar, which he won with Matt Damon in 1998 for their breakthrough hit Good Will Hunting.

It's certainly not uncommon for extensive rewrites to happen while any major movie is in production, but it's intriguing that Ben Affleck may have made these tweaks while wearing the iconic Batman costume. Regardless, it seems Warner Bros. was pleased enough with Chris Terrio's work on Batman v Superman: Dawn of Justice, since they also brought him aboard to write both Justice League Part 1 and Justice League Part 2 for director Zack Snyder.

Production on Justice League Part 1 is expected to begin this spring, after the cast and filmmakers finish promoting Batman v Superman: Dawn of Justice. Just a few months later, Suicide Squad hits theaters on August 5, with production currently under way on Wonder Woman. We'll have to wait and see if Ben Affleck performs any more rewrites in his Batman costume as the DC movie universe continues to grow.
