Directed by: Richard Fleischer

Continuity mistake: When Thorn goes back to Simonson's apartment to see Shirl, he interrupts a party. Shirl is holding a drink which contains huge ice cubes, but right after the two of them go into the bedroom the ice is no longer in the drink. Way too fast to have melted.
Hatcher: So, you finally made it. Do you know what time it is?
Det. Thorn: You tell me. You're the only one here who has a wristwatch.
Hatcher: I can't. The damn thing won't run.
Trivia: This was Edward G. Robinson's last film.
