While audiences this weekend are sure to marvel at the action sequences of "Man of Steel," it's Hans Zimmer's music that will be the unseen star of the show.

Arguably one of the greatest composers in cinema, Zimmer is the Oscar-winning mind behind classics such as "The Lion King," "Gladiator" and "Driving Miss Daisy." He was the latest guest for CNN Radio Music Notes, where he opened about his making the music for "Man of Steel," his writing process and some of his fondest memories along the way. Here are a few quick bites from Zimmer's chat with CNN Radio.

CNN: How did you settle on a musical theme for "Man of Steel?"

Zimmer: The clue, the hook for me, the way in was isn't it about time we just put our cynicism aside a little bit and just celebrated honest people – folks, farmers, people that leave their doors unlocked in the Midwest, people who don't make the news. This idea of where do you belong, who do you listen to, and ultimately this sort of quest which I think all of us in one way or another have – how do you become more human?

CNN: Despite your success, you say there's a process you always have to fight your way through when starting a new movie?

Zimmer: The blinding fear of the blank page. There was a lot of procrastination and re-evaluating one's self worth and all that ... each one gets harder. Every new movie you're being asked to re-invent yourself.

CNN: What makes memorable movie music?

Zimmer: Ultimately, I think it's the story. I try to not to objectify the music so where it sort of sits on top of the movie. I try to have it come out of the screen, I try to create a sonic world that the characters can inhabit and I slither into the sound design area more often than not.
