When talking to Total Film magazine (via Coventry Telegraph), Snyder let it be known that John Williams’ theme will not be appearing in the movie.
“We decided to act as if no Superman film had been made – even though we love the films that have been made. We had to say this is a Superman movie for the first time and you can’t then go ‘Oh, now let’s steal a little music. So, yes it’s awesome music but Hans Zimmer is going to do something awesome.”
Talking deeper about his approach to the character, Snyder offered this: “We have great respect for the canon. I would say it is a clashing of stories and ideas. Superman is the king-daddy of all superheroes – to make him work is a big deal. The big challenge is if you can make people feel ‘What would you do if you were Superman?’ That’s what we went out to do as far as we could. Superman’s always been this kind of big blue boy-scout up on a throne that nobody can really touch, so we tried to make him relatable.”
