“And then the studio got a single Superman script I think from JJ Abrams at that time, and [Warner Bros. chief] Alan Horn was so torn – because it’s such a fascinating concept to do a Batman versus Superman film. And I still think it would be to do that. But the studio decided to try [a] separate version of Superman and Batman, and then maybe think about down the road if you want to bring them together in one film,” Andrew Petersen said. Eventually, Christopher Nolan chose to cast Christian Bale as Batman for his highly successful Batman trilogy.
