HELP! Scripts for Spiderman Trilogy

I plan on editing my own version of the spiderman trilogy, but before I start actually editing, I want to work it out on paper first. I have all the ideas in my head on how to unite all three movies into one fanedit, but I can't find anywhere on the Internet the screenplays for all three movies so I can make my changes. I would really appreciate if anyone could find any of the three screenplays. And the version that was actually shot and released, not an early draft or the cameron version! Thanks
