George Lucas asked David Lynch to direct "Return of the Jedi." It's very difficult, but mind-meltingly fun, to imagine how that movie might have turned out.
The only thing I know about "Return of the Jedi" that most people don't is that I went to college with a super-nice girl who played an Ewok. She was a little person and we worked the same student job together--I drove double-decker buses and she was one of the conductors in the back who got passengers on and off, signaled stops, punched transfers, etc. During summer vacations she went off and made movies (and has continued to, building a very successful career in film and TV). You know that scene where two Ewoks get blasted and one crawls over to its dead mate? She was the Ewok who lived. I'd mention her name but I'm afraid she'd Google herself, read this post, and tell y'all she has no idea who I am, which would completely ruin one of my few "brush with greatness" stories.
