I don't really get into a big intellectual analysis of why I am going to do a certain script or not.
With a film, you have to pare down and take stuff out and squish it all down into a 110 page script.
I'd love to be involved in the process of adapting a book to a script, but that's simply not my job.
The approach I take in selecting a script is based on what I fancy from the the scripts I'm offered.
A script can just be a blueprint, and you've got to go in and build it and color it in and paint it.
If you just want ten songs to fit somebody else's script, then I'm not really the composer for that.
