Historically, there is a fight between the sound designer and the composer. You see them in the mixing room and they're always fighting because the composer wants the music to be heard and the sound designer wants the sound to be heard.
Alfonso CuaronAs a director, you're only as good as your collaborators. You surround with collaborators that are going to understand what you're trying to do. Not only that, they're going to push and fight for what you're trying to do.
Alfonso CuaronI have my set rigged with the biggest sound system possible and have a mini jack for my iPod attached to my director's chair. I find playing music is a very direct way to communicate with actors and the crew, especially those crew members who are on the periphery of the set. I like dancing on set too, it's a good way to release tension.
