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.
Okay this is interesting, I never knew there was any carryover in terms of Rebel extras. According to Wookiepedia, however, bafflingingly in Empire he is not only not playing the same character from the first film, he’s actually playing two different characters, both who aren’t his character from the first film.
