Continuity mistake: When Falfa's Chevy flips over, we can see that it has no fuel tank at all in it. However, in the next shot the car now has a visible fuel tank, and it explodes.

Terry Fields: Pardon me, sir, but I lost my I.D. in... in a flood and I'd like to get some Old Harper, hard stuff. Would you mind buying a bottle for me?
Bum at Liquor Store: Why certainly! I lost my wife, too - her name wasn't Idy, though, and it wasn't in a flood - but I know what ya.
Terry Fields: Thanks, here's enough for a pint.
Trivia: Harrison Ford wears a white cowboy hat in the film, because George Lucas wanted him to get his hair cut in the 1950's "crewcut" fashion. Ford didn't want to because it was in style to have longer hair at the time and he was afraid it would affect future acting jobs if he cut it. He convinced Lucas to just let him wear the hat to cover his hair.
