George Lucas' relationship with Disney is relatively new . . . but his love for Disney goes way back.  How far back?  Check this out . . .

I don't know how this went unnoticed for so long, but Lucas slipped an homage to Disney into the "Star Wars" movie "The Empire Strikes Back" . . . which came out 33 YEARS AGO.

Someone just discovered that during the fight between Luke Skywalker and Darth Vader, there's a crystal Mickey Mouse head clearly visible in the background.

And it's definitely legit.  If you have the DVD, you can check it out for yourself.
