I'm a big collector of vinyl - I have a record room in my house - and I've always had a huge soundtrack album collection. So what I do, as I'm writing a movie, is go through all those songs, trying to find good songs for fights, or good pieces of music to layer into the film.
I just grew up watching a lot of movies. I'm attracted to this genre and that genre, this type of story, and that type of story. As I watch movies I make some version of it in my head that isn't quite what I'm seeing - taking the things I like and mixing them with stuff I've never seen before.
To me, movies and music go hand in hand. When I'm writing a script, one of the first things I do is find the music I'm going to play for the opening sequence.
Movies are my religion and God is my patron. I'm lucky enough to be in the position where I don't make movies to pay for my pool. When I make a movie, I want it to be everything to me; like I would die for it.
