Only just recently noticed this in Empire, but I don’t know if I really noticed it or if I think I noticed it.
The guy in Star Wars who says “enemy fighters coming your way” is, I think, in Empire too? As the same rebel?
I looked it up and apparently that guy’s name is Del Goren, played by Burnell Tucker. IMDB is showing that Burnell Tucker is also in The Empire Strikes Back, and I think he’s the guy who is monitoring the Imperial Probe Droid transmission before Han and Chewie go out after it.
