Looking around for info on new films I found a mine of reading material if you can visualise in your head. All the sites below offer scripts or transcripts of films that may or may not have been made. If you find them, look for the early drafts- it's very interesting how different the version that ended up on screen can be. As an example of this, here's Back to the Future's original draft. Not as family-friendly in this version!
