Divers: 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.
Continuité: 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".
Continuité: 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.
Erreurs factuelles: The plane holds just one bomb but nonetheless multiple explosions occur when it attacks.
Continuité: 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.
Considéré à tort comme goofs: After Frankenstein has reaches the finish line, a shot clearly shows him using his right hand to lift himself up and out the car, despite his navigator having removed it just a couple minutes before. This is because this is actually the navigator posing as Frankenstein. This shot is a clue to Frankenstein's final ruse, and thus not an error.
Equipe ou équipement visible: Cameraman and camera visible in reflection of trumpet in opening shot.
Erreurs dans la géographie: The racers are shown driving through mountainous terrain even when they are supposed to be in parts of the country such as New Jersey and Missouri that don't have any mountains.
Erreurs dans la géographie: The shot of the racers in Manhattan en route to the Lincoln Tunnel was clearly filmed in downtown Los Angeles.
