One Big Way 'Batman V Superman' Will Be Different From 'The Dark Knight'

'You're scaring me right now.'

Now that Christopher Nolan has officially broken ties with WB's Justice League plans, there are only two people with connections to Christian Bale's and Ben Affleck's Batman: writer David S. Goyer and composer Hans Zimmer.

After "The Dark Knight Rises," Zimmer wrote the music for "Man of Steel," so his return for "Batman V Superman" makes sense. But "Dawn of Justice" provides a particular challenge for the composer, making music for a character you've already scored but without repeating yourself.

When we spoke with Zimmer on the carpet, he explained how he dealt with the problem.

"Chris and I spent nine years in the world," he said. "I didn't want to dishonor the work we've done, so I came up with an easy solution."

That solution is "Mad Max: Fury Road" composer Junkie XL, "somebody who is new to it," as Zimmer describes him. "I'll stick to the Superman guy."

Zimmer hasn't completely rid himself of the Batman, however, since he'll still consult with Junkie XL about the themes.

Batman isn't the only hero causing Zimmer grief on the "Dawn of Justice" job. He'll also have to compose for Wonder Woman, Aquaman and Cyborg at the very least, and possibly even The Flash.

"There is a lot to compose. You're scaring me right now," he said. "Righteously so, I'm just starting to think about it. There comes an enormous responsibility because they're all iconic figures, and they're beloved. And so you just want to be very careful that you serve them with respect."

"Batman V Superman: Dawn of Justice" opens in theaters on March 25, 2016.
