There's been plenty of speculation about how much of the final product is Snyder's and how much is Whedon's. Elfman says that much of the film was being shot as he wrote the score, and that he never scored any of the retooled Snyder footage that didn't make it into the film. Things were so last-minute that at times he wouldn't be composing to actual footage.
"I had a lot of storyboards in place of action. There would be full scenes and then a five-minute sequence of storyboards. Honestly, it was like working on an animated film," says Elfman. "I didnt score any of the unused footage, the movie that came out is the movie I scored, it was just in very rough form."
