Corrected entry: Just before Leia and Luke swing across the chasm in the Death Star (and at other times), the "blasters" they are shooting are seen to eject shell casings. This is because the guns used in the movie are just dressed-up blank-firing prop guns.

Corrected entry: In the battle between Darth Vader and Ben, just before the scene switches to Han and Chewbacca, you can see that in the last three hits, Ben's lightsaber has no colour, and it looks like it starting to die out.
