Factual error: When Lonegan brings the briefcase full of money to the cage for his big bet, all of the 100s in the case are new federal reserve notes not the type of the 1920s.

Continuity: When Hooker is taking Lonegan to meet his Western Union tipster, he gives Lonegan's driver an address. When the car pulls up to the destination, the number on the building is different.

Continuity: When Hooker meets Gondorff for the first time, he puts him in a shower, fully dressed. When the camera cuts to a front view of Paul Newman, as the shot goes back and forth between him and Redford, Newman's right pant leg alternates between being soaking wet and completely dry several times.

Continuity: In the scene were Lt. Snyder breaks the phone booth window with his gun and points it at Hooker, Hooker's hat falls off. Yet in the next shot over Lt. Snyder's shoulder you can see that Hooker's hat is back on his head.

Continuity: When Lt. Snyder meets with Polk, the FBI agent, they both sit down and Snyder makes a comment about Polk's "nice office," which is really an empty factory. Polk gets offended immediately and from an over-the-shoulder shot you can see him rise from his chair. The camera switches to a shot of his face and he's calmly sitting down again, then rises up in anger. He stands up twice.
