Continuity mistake: About 25 minutes into the film, Vincent Price puts two vampire bodies into the back of his station wagon. Viewed from the open rear door, the woman is on the right side face up and the man is on the left side face down, and he drives off to the pit. In the next scene, he parks the car at the pit and when he goes to unload the bodies, the woman is now on the left side face down and the man is one the right side face up. For people who have died and then been killed again, they sure did move around a lot in the back of that car.
Factual error: The movie shows a 'jet' aircraft belonging to 'consolidated airlines'. The so called airplane is a laugh. It has two jet engines attached to the horizontal stabilizers. The landing gear appear to be bolted to the wings. During the movie this plane crashes and the engines are moved to a terminal to be examined. They are too small to be real engines. During the course of examining the engines, they are run inside the terminal building. One of the investigators stands 10 feet behind the jet intake and is not sucked inside. The cockpit is not even close to what one would find in a jet airplane.sexxypeety
Continuity mistake: The three enter a small cantina and start a fight and fire. The place is huge on the inside, with stairs to a second floor. From the outside it's just a small shack.
