Audio problem: In the scene after Reese Witherspoon and Luke Wilson are returning from questioning the ex-wife of the murder victim at a spa, they are driving up in Luke's car. You can clearly see, as they get closer to the camera, that what you hear Luke saying isn't what his lips are saying. It was a very obvious dub over...and a very bad one.

Audio problem: (May only apply to the original VHS release.) When Scar has Zazu locked up in a cage, Zazu mentions Mufasa's name and Scar yells at him, "What did you say?" Right before Scar's actual line, whilst Zazu is talking, you hear Scar's "What did you say?" line very faintly in the background, even though Zazu has not even mentioned Mufasa yet.

Audio problem: The aliens that populate the planet of Geonosis have an extremely peculiar method of speech - consisting of clicks and weird ringing sounds. However, despite the fact that they make up 99.9% of the crowd in the arena, the sound of the crowd cheering is human. (01:44:10)

Audio problem: At the beginning, when they steal the dolphin, you hear the peel-out sound effect as if the truck was on a paved road, but they were on grass. (00:07:15)

Audio problem: When Chunk flags down the car for help, he finds Jake Fratelli, who begins to sing loudly in Italian. Chunk screams, and as we hear Jake continue singing, we see his reflection in the side-view mirror as he is smoking a cigarette silently. (00:49:00)

Audio problem: In the lobby shootout scene, when Trinity starts kicking one of the guards after he goes to reload and reaches for a new clip, you can hear her yell the first time she kicks him, but the next two times, although her mouth opens the same way, the audio's been silenced. (01:38:20)

Audio problem: Just before the crashed jet skids to a stop, you can hear the jet engines despite them being ripped off with the tail fin quite a way back, so you shouldn't be able to hear them.

Audio problem: While describing Miss Rhode Island during the Top 5, Kathy continues to say, "with a minor in elementary particles" however when Kathy can be seen on the live feed of the jumbo-tron onstage, she is just smiling and not saying those words. (01:32:20)

Audio problem: In the scene where Leo explains how he launders the drug money and Roger says "You're a cheat", Leo says "Come on, everyone cheats a little, look at the pentagon." But when he says "look at the pentagon", it's dubbed in because the sound of his voice doesn't match his other dialogue, and if you read his lips it doesn't match either.

Audio problem: When Will Smith is looking at the two space ships at the MIB headquarters, if you look in the background Zed and K are there typing on the computer. But if you look closer you can tell that they're not even touching the keyboard and the sounds are just added into the movie. (01:16:00)

Audio problem: When the cop saves the girl from the mob of locals, his car tires squeal as he accelerates away, but the car is on loose dirt, which makes the squealing impossible.

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.
