Visible crew/equipment: Near the end, when Rodmilla and her daughters are requested to appear before King Francis, in the first shot facing the king and queen, there is a beige narrow mat in front of the large patterned rug, which is not in previous or following shots, specifically used for crew/camera tracking (fullscreen version). (01:50:30)

Continuity mistake: In the scene where John is peeing off Stifler's balcony, he knocks over a plant and knocks out Christy. In the next shot the plant is back, and in the one after that it is gone again. (00:17:15)

Continuity mistake: The morning after Vivian's first night at the hotel, room service brings breakfast. When she's eating a croissant it cuts to a shot of Edward, and when it cuts back to Vivian she's eating a pancake which goes from being half done, to being a whole pancake again. (00:30:55)

Continuity mistake: During the scenes at her Mother's house, Kate's hair goes from blonde to REALLY blonde.

Factual error: The terrorist with the AK47 is unaware of the fact that a Harrier is hovering just outside the window until he slowly turns and see it there. He does a double take when he sees the Harrier just five metres away! A Harrier is an incredibly loud aircraft; you can hear them from three kilometers away. At that range the floor would shake with the noise and he would have been in no doubt whatever that he had been under attack for some time.

Continuity mistake: When Hal's co-workers bring him a cake for his promotion, Rosemary takes a slice out for herself. They change shots a couple times, and the size of the piece missing from the cake changes several times, and the layers of the cake change as well.

Other mistake: The envelope with the letter for Amanda is suddenly in a very good condition as it ends up in the peanut bowl... even though it has been in the trash, had chewing gum attached to it, been trodden on, had a beer barrel rolled over it, etc....

Continuity mistake: When Bullock is warning Reeves of the coming winter blizzard, she is looking through pictures that depicted her and her friends enjoying the snow. She then turns to the dog and asks "Remember that day? You were not happy". However it's revealed that both characters have the same dog, given to Bullock's boyfriend by Reeves, so when the snow happened in Reeves' time - 2004 - the dog was with him.

Continuity mistake: At the beginning of the movie, Harry's van has bucket seats, yet later on when the "gas-man" rides along, he is sitting on a bench seat in-between Harry and Lloyd. (00:38:00)
Suggested correction: Mental isn't sitting on a bench seat, it's implied he's sitting on the floor of the van in between the both of them. Although hard to see, the backs of the bucket seats can still be seen behind Harry and Lloyd at certain points. You see a fair bit of it behind Harry whilst he's dancing as Lloyd sings the line "and if that mocking bird don't sing".

Continuity mistake: After receiving the phone call from Nancy, when Robert and Morgan are talking in the taxi, his seatbelt repeatedly changes from over to under his trench coat collar. (00:16:45)

Continuity mistake: After being chased by soldiers after talking to his uncle, Dastan gets into a swordfight with Garsiv. As soon as it starts, Garsiv hits a pillar with his weapon knocking a significantly large chunk and a another smaller chunk out of it. In the immediate shot, the size and locations of the two chunks differ.

Character mistake: On the day Rebecca arrives home, Junior Douglas says that he was "Valedictorian, Class of '95." Earlier, Drago talked of almost killing Running Buffalo "during that trouble back in the '40's," which would have been about 50 years earlier. That would mean Drago and McLintock were fighting Indians when they were babies, or possibly before they were born!

Factual error: In the montage sequence showing Drew Barrymore hanging out with the math club, they have a Pi poster with 3.1457869986. Only the first 3 digits are actually correct. (Pi = 3.1415926535897...) (00:25:20)

Continuity mistake: During the first scene set in a prison cell, as Martin Luxford (played by Hugo Speer) is about to be released, there is a glitter ball made from an orange covered in tin foil. It is rotating first one way and then the other, as it has been spun by hand. As the film action cuts between the two characters, the ball mysteriously changes direction without having slowed down and at one point appears stopped, having previously been rotating rather fast.

Revealing mistake: When Marin and Jack Nicholson first enter her mother's house, Marin is wearing white pants, and it is noticeable that she has a thong on. When she gets into bed with Jack, she is in full underwear.

Visible crew/equipment: After Mike and Alex get home, when Scarlet walks in and asks Alex how the tryouts went, the tape mark is visible on the floor in front of Alex, while he's sitting. (Visible on fullscreen version.)

Audio problem: When Reynolds is salting the asparagus the camera cuts back to Alma and you can see Reynolds' hand moving in a different direction but the salt shaker sound is still playing. The camera cuts back to Reynolds, and he's holding the salt shaker again. (01:06:15 - 01:06:39)

Revealing mistake: While Akeem is getting his hair cut, you can see the reflection of the white character he plays in the mirror. It is quite obviously a stand-in, with a fatter face and different glasses. (00:33:45)

Factual error: The movie and events take place in 1958. However, two Fender amplifiers that are used by the band, "Johnny Casino and The Gamblers" are "Silverface" models that were only manufactured between 1967 and 1981.

Continuity mistake: In this scene we see John Wayne and others milking goats. The goats then get startled by a baby elephant and Wayne falls backwards on to the ground and you can see he takes the bowl with his right hand and the milk is thrown out of the bowl. In the next shot of him close up the bowl is on his head like a helmet when the bowl never even went on his head as he fell backwards. (01:09:20)
