Trivia: When Luke escapes for the first time, he is being chased by a loose dog dragging a leash. Luke jumps over all kinds of obstacles to make it tougher for the dog chasing him. Finally, Luke dives off a bridge into a stream. In the theatrical version, the dog also jumps off the bridge, but the leash gets caught on the bridge and the dog gets hung.Quite a shocking sight. In the videotape and other releases, the dog boss (Anthony Zerbe) claims the dog died from exhaustion, you never see the dog get hung.
Trivia: We never actually see Posey (Clint Walker) die on film. We know where he is during the mission and we only saw his partner Bravos get shot but not Posey. I always have this funny feeling that he may have survived and the surviving members (Lee Marvin, Charles Bronson, and Richard Jaeckel) of the Dozen forgot about him.

Trivia: During the title sequence, as Millie is buying a pack of cigarettes from a vendor her undergarment breaks, the vendor stares at her in surprise, and she does a slight curtsy and walks away. When the film was originally released, that was followed by a quick shot of the vendor looking down and seeing Millie's broken undergarment lying on the sidewalk, but for some unknown reason that shot has been deleted, at least from the version on VHS and the one shown on TV. (I don't know whether it is included on DVD.).
