Revealing mistakes: In the BiKeHEaD scene, the car is clearly parked in front of a wheat field (the person walking in front of the car does so to give the impression of movement). Also, on the shots from the side of the car, if you look closely you can see that the car doors are opened to allow the cameraman to see inside the car (Honda Elements have suicide doors).
Revealing mistake: Matt S can be seen moving after he is supposed to be dead.
Revealing mistake: In the shot of Benetiz with flames that is repeated throughout the movie, the actor who played the lab technician in the Edgar Snow scene can be seen walking down the stairs.
Revealing mistake: When Edgar Snow is walking through the town, it is apparent that his beard is loose at several times.
Crew or equipment visible: When Edgar Snow is walking through the town, Steve can be seen filming the shoot when Edgar walks past a glass door.
Audio/visual: The person making the screams supposedly of Edgar Snow when he dies, clearly is not the actor who played Edgar, but was recorded by someone else and added in later.
Errors made by characters: In the scene introducing Murdoch, Eric picks up the cereal bowl with the wrong hand.
Incorrectly regarded as an error: After Murdoch crashes his car and is talking to the CB radio, the scene goes blank while the bear road head in two different cars traveling in different directions incident is described. This is not an error, but was used as a filming technique because the actual scene would be impossible to film (and probably rather disturbing to watch).
Revealing mistake: During the commercial Little Shanghai is making, it begins to get dark outside. Kelly does not have time to memorize the lines because soon it will be too dark to film anymore, so it is obvious that she is reading off the script.
Crew or equipment visible: In the same scene as above, the script is visible on the left of the screen.
Audio/visual: In the scene where Chandru is captured, Kevin is obviously not the person making the screaming noises.
Continuity: In the scene where Chandru is in Ben�s lair, it appears that Chandru�s hands are bound together, but after Leonard and Part 6 fuse together, Chandru is able to move his hands around freely.
Revealing mistake: The doors that Humpman knocks on do not correspond to the interiors of the houses that he visits.
Continuity: After the tennis scene, Billy says the cleaner can also be used as a low cost, highly efficient spermicide. But later in the movie it is revealed that the same cleaner is used to impregnate Hugh Tide.
Audio/visual: During the hunting scene, when Ben says �so be it,� the recording of him saying that is played twice, although his lips are clearly not moving the second time.
Revealing mistake: When Ben and everyone are driving to get to the competition, Ben�s car is clearly not moving. A crewmember is seen pushing a prop to give the impression that car is moving.
Crew or equipment visible: When Murdoch jumps out from behind the couch, a crewmembers arm can be seen to the right of the screen.
Audio/visual: When Benetiz is dying and Murdoch shoots him to end his misery, the audio of the gunfire does not correspond to the actual firing.
Continuity: Although the events in the scene where Murdoch jumps a fortified wall are supposed to take place immediately after Murdoch shoots Benetiz, Murdoch can be seen wearing different pants in the two scenes.
Continuity: The castle (supposedly Billy�s lair) Murdoch can be seen approaching is not the actual building he enters.
Continuity: Early in the movie Murdoch says he has been a park ranger for 8 years. But Billy says Murdoch was born only 19 years ago. That would mean Murdoch has been a park ranger since he was 11, which does not make much sense.
Continuity: The length of Murdoch's beard varies in consecutive scenes
