Re the shoe, I've never seen it but I've read several pieces over the years referring to it.
I'm pretty sure it is in the 2nd movie ("Empire Strikes Back"??), and is during a dogfight between X-wings and the bad guys. It is only ever in the background and off to one side, so you don't ever focus on it unless you're looking for it. It's a regular white basketball sneaker-shoe, sized the same as a starfighter, and was an "in-house" joke at the time.
Happy hunting! :green:
