Rio Bravo (1959)

Continuity mistake: When Rick Nelson tells Angie Dickinson to throw the plant pot through the window to distract the gunmen who threaten John Wayne he seems to have had a hair cut between scenes as his sideburns are halved by the time he reaches the street and grow again later.

John T. Chance: Sorry don't get it done, Dude. That's the second time you hit me. Don't ever do it again.
