Script please

I wish to write an alternate version of the two films, with some added characters and creatures. There will be antagonists other than Luke in them, as well as a third completely-original film. However, in order to get started, I require a script of the films. Ideally, it would contain no differences from the films, containing every action and word, as well as who says or does the action or word. I at least require what they say. Please help me in my search.
