David Lynch directed Return of the Jedi. In our universe, he turned down the job when George Lucas offered it to him.

The mind reels. Would the forest moon of Endor have been covered in Douglas firs? Would Luke have had visions of midgets? Would there be vague references to Eastern mysticism, and gruesome exploitation of women? In short … would it have been all that different? Meanwhile, in this universe, someone is probably working on a Jedi–Blue Velvet mashup at this very moment.
