The initial scenes are set in the city of Veracruz but were filmed in Tehuacán. While the action is still taking place in Veracruz, the name Tehuacán can be seen on a building.

When Duke Halliday falls off the side of Jim Fiske's car, he lands on his left arm and is seen rubbing it. In the next scene, while speaking to Inspector General Ortega, Halliday is rubbing his right arm.

During the car chase, the Graham/Halliday car looks as if it's going faster during the in-studio shots than it does in some of the corresponding location shots.

During a car chase, the Graham/Halliday car runs over a chicken, leaving it fluttering in the road. When Blake's car passes the spot, the chicken is gone.

Capt. Blake kicks in the door of Lt. Halliday's cabin, whilst Lt. Halliday is in the process of getting dressed, doing up his tie, and turning the shirt collar down. Capt. Blake throws Lt. Halliday's jacket to him, and in the next shot, he is adjusting the shirt collar again. However, the collar is not completely turned down; the tie is showing underneath and now with the jacket on, this has the collar half turned up. Cut to the next shot, when Lt. Halliday goes to pour a drink, the shirt collar is now turned down, no tie is showing, but the jacket collar is now fully turned up. In the next shot, Lt. Halliday turns the jacket collar completely down and ends up in a fight with Capt. Blake.

Outside the hotel, Blake tries to start the car; it turns over but does not start. He then sees the ignition wires cut, which means the starter would not have engaged.
