Warner Bros. has yet to comment about any of the rumors associated with the production, but producer Charles Roven is dishing details.

Roven visited Loyola Marymount School of Film to do an interview with their “The Hollywood Masters” series. Roven dished the reasoning behind Ben Affleck’s casting as the production was looking for someone who looked like they could take down Superman.

"He was the first guy we went to, that's who we wanted,” Roven said. “We knew that we wanted a very mature Batman, because we wanted to juxtapose him with this very young Superman. So we wanted a guy, who was tougher, rugged, who had signs of life, who had lived a hard life, and we wanted the guy to have chops for sure. So when we went down that list, there just weren't a tremendous number of guys who could carry that. We also wanted a guy with big stature. Ben is 6-4. Henry [Cavill] is a 6-1.”
