The Hustler (1961)

Continuity mistake: In the scene depicting the first game between Eddie and Fats, having just broken off in the first frame, Eddie chalks his cue with his left hand while his right hand is placed towards the butt of the cue. In the next camera shot however (a split-second afterwards), Eddie is chalking the cue with his right hand with his left hand positioned on the upper half of the cue. As a result, the background scene contains a continuity error also - the man with the striped tie is seen putting a cigarette to his mouth in shot 1 but his cigarette is down by his knee in shot 2.

Fast Eddie: I'm shooting pool, Fats. When I miss, you can shoot.

Trivia: In 1973, Paul Newman played Henry Gondorff in "The Sting." Jackie Gleason later played the same role in the film's sequel, "The Sting II."
