For the curious, here is the original 4 page prose sketch for Looper, written in 2002.
At the time we were still trying and failing to get Brick made, and out of frustration I started writing short ideas that we could film with no money. The Psychology of Dream Analysis was one that we actually made, this was another (though we never ended up shooting it.) It sat in a drawer for seven years, until I pulled it out and used it as a sort of treatment for what became the full script. It’s both very different and very similar to what we ended up with on screen, I hope it’s an interesting read. Let me know what you think.
