Since Hans Zimmer provided the score for all three of Christopher Nolan's The Dark Knight movies, and Zack Snyder's Man of Steel, fans may think he's a lock to do the music for Batman vs. Superman (a.k.a. Man of Steel 2). When asked if he would come back for the sequel, on the red carpet of the Rush premiere, the composer gave this response.

"This is really complicated for me. Because we all went, 'Okay, we're done with Batman,' and now it's sort of getting smuggled back in. I'll have to have a think about that one. I might give you a new Batman if I do it."

He also spoke about the news that Ben Affleck is portraying Batman.

"I actually think it's a really good choice, because, number one, he's a great filmmaker. He's smart. He wouldn't have taken it if he had set himself up for a fall. And, you know, he's a bit older these days and that's what we need, and he's got a good chin."

Zack Snyder is directing Batman vs. Superman from a screenplay by David S. Goyer. It isn't known when production may begin.
