There's a film editing error when Joel (Melvyn Douglas) wakes tied up after being kidnapped, and says, "Oh, what happened to my head?" Terison (Nat Pendleton) is playing cards. He stops playing, looks up and starts to answer. There's a cut and Pendleton stops playing (again), looks up, and answers.
In the final scene, Joel -- who earlier had been shot in the derriere and was given an inflatable "donut" to sit on -- cringed as he sat on Garda's lap. But previously he had sat several times -- such as when he was tied up on the chair, when he was in the car, and on the edge of the desk -- without showing any pain.
