Audio problem: When we see the can-can dancers perform on-stage, the music is played by a full band including brass and drums, despite the fact that there's only a pianist on-stage. (00:22:10)
Suggested correction: This error is not unique to Carry On Cowboy. It seems that in very many western movies (and TV shows) there might be a scene in a saloon, in which a singer or some dancers are performing on a stage. In nearly all such occasions they seem to be accompanied by a full orchestra which is nowhere to be seen.
This is not a valid correction. To say the error exist in other films does not invalidate this error.
Sorry, I think I got that wrong. I was not trying to invalidate the error, far from it! What I meant to say was that I agree that this is quite an obvious error in Carry On Cowboy, and that this also seems to be a common, and rather amusing, error in many other western films as well.
Unfortunately at this time, valid mistake entries are not subject to forum discussion where one agrees or discusses the mistake. Just give the mistake a thumbs up if you agree with it.
Plot hole: Even if the white blood cells will attack and destroy the sub and the body of Doctor Michaels the atoms would still remain and take normal size after the critical 1 hour is up. This would also apply to the laser gun which they forgot or left behind on purpose, as well as several dozen litres of saline solution which were miniaturised and pumped into Benes' body. He's in a lot of trouble.
Continuity mistake: When Don Knotts is in the old Simmons mansion, he falls down a chute of some kind. If you watch closely you will see the stunt person looks nothing like Don Knotts. It is a younger man with very straight hair.
Continuity mistake: When the Batmobile is going to park (before the bomb scene) there is a sign saying "Mobey Dick Parking Only". When he is later carrying the bomb and passes by the Batmobile the sign is not there.
Factual error: John Wayne and James Caan are in the gunsmiths shop, and behind the gunsmith on the shelf are some products, one of these products is Bugler tobacco. Bugler tobacco was introduced in the United States in 1932. (01:00:00 - 01:02:00)
Other mistake: In the very last scene of the movie, and just before Blondie shoots the rope that is holding Tuco on the grave's cross. You can see a car moving in the background, screen right of Tuco's head.
Visible crew/equipment: In the scene where Jeremy Kemp and George Peppard are playing daredevil in their planes and Kemp's plane hits a brick tower there is a shot of the plane plummeting to the ground. The alert viewer can see the shiny metal wires that were used to support and guide the plane on its way to the ground.
Visible crew/equipment: When Paul Newman takes Julie Andrews up a small hill to explain that he is not going to work for East Germany you can see a shot from a distance. It is clear that this scene was done in a studio, as you can see several lights above the blue background (which is supposed to be the blue sky).
Factual error: Adam, who was not born of a woman and who would have no need for an umbilical cord, has a navel. (00:09:45)
Continuity mistake: At the end when the sled full of Christmas stuff is on the mountaintop, it starts sliding off the edge. It's going fast enough that it should be long gone by the time the Grinch reaches it, but when he does it's still right near the top of the mountain.
Other mistake: When Snoopy starts sneaking through the pumpkin patch, Sally is standing with her arms crossed and Sally's hand is painted blue while talking to Linus. (00:20:35)
Revealing mistake: As Jango fires the machine gun, the ammunition chain hanging from it is loaded on both sides, and it doesn't move. Also the belt has different sizes of cartridges in it. (00:45:30)
Revealing mistake: Near the end of the film when a building is collapsing and people are running to escape the falling debris, several women along with James Coburn are running up some stairs; a block of cement falls and hits actress Gina Golan right in the head. Instead of killing her on the spot, the bolder merely bounces off her head and she continues running up the stairs. (01:40:55)
Revealing mistake: Although "Man" is supposed to be completely naked, there are several shots where his flesh-colored briefs are visible. Most noticeable when he is initially set loose to be chased.
Factual error: In the scene near the end of the film where Victor Buono is sitting in his chamber addressing his two captives, he opens a can labeled egg foo young with a can opener. He pours the liquid contents into a bowl. Egg foo young is an omelet and could not have passed through the small holes made with a can opener.
Visible crew/equipment: In the scene where Sgt. Bung wakes up in the bath, he hits his head on the copper water boiler. However, you can see the white padding that will protect his head stuck underneath the bottom of the boiler. This is visible throughout the scene. (00:57:15 - 00:58:00)
Deliberate mistake: When Raza is chasing the "empty" train, as it goes over the trestle just before he stops it, you can see the engineer in the train's engine.
Continuity mistake: When Peter O'Toole is locked in the closet at the museum, he puts a rope through the keyhole and uses a hook to pull it under the door. In the first shot, from outside the closet, the end of the rope is to the right. In the next shot, from inside the closet, the end of the rope slides under the door to the left. (01:22:30)
Visible crew/equipment: When Charles Hawtrey "jumps" onto the light near the end of the film you can see the strings pulling him across. The same can be seen with Jim Dale as well.
Audio problem: During the chase at the end of the movie, the police cars' tires squeal in the dirt.
