In watching some scenes frame by frame to get just the right shot to compare, I ran across something that I can't believe I've never heard before.
Here are 4 frames from Greedo shooting first:
Do my eyes deceive me or does it look like Han shoots twice? The first shot goes right through Greedo! Is one of his shots left over from 97, or even 77?
Just in case your wondering, this shot of the film isn't even in Revisited to compare.
