Miscellaneous: In the theatrical version and all video versions up to the "Roger Corman's Classics" release, there were some errors that have since been corrected. Traffic has been cropped from the shot when Machine Gun Joe runs over the man hanging the "Frankenstein" banner on the street (which previously made nonsense of the earlier newscast of "citizens staying off the streets"). A crewmember previously visible when Joe runs down the fisherman has also been cropped out.
Continuity: Although the movie refers to the country as the "United Provinces of America", a banner can be seen near the start of the movie as Machine Gun Joe pulls into the raceway that says "United States".
Continuity: When the "bullifighter" challenges Calamity Jane, there is a quick close-up of a spinning wheel whose rim different than those on Jane's car.
Errors in geography: The opening sequence occurs at "New York Memorial Raceway" yet mountains can be seen reflected in the glass on the grandstands. (Scene was filmed at Ontario Motor Speedway in California.)
Factual errors: The plane holds just one bomb but nonetheless multiple explosions occur when it attacks.
Continuity: During their last stop at Albuquerque, near the last scene before resuming the race, while talking to Frankenstein, Annie slips off a stocking. Then, after the camera goes from Frankenstein back to her, she is again taking off the same stocking.
