Revealing mistake: Prior to the animal show, just before Harry feeds the second dog, you can see someone in the back throw a treat through the curtains to get the dog to go up front. (00:02:50)
Revealing mistake: When Lloyd and Mary are going to the airport, you can see a white van out the rear window. The driver is turning the steering wheel, but he keeps going straight. (00:04:30)
Continuity mistake: When Lloyd is driving Mary to the airport, at one point he says "What's the matter, nervous about the flight?" When he says this look at the white van in the rear window, it's right up next to the limo. However when the shot cuts to Mary it's already several meters behind them despite the very slow movement the limo has made. (00:04:30)
Visible crew/equipment: In the shot just before the Sheep Dog van flies up and lands on the road, a shadow of a camera mounted to the side of the Sheep Dog van is visible as Harry nearly runs over the running man. (00:06:10)
Continuity mistake: When Lloyd drops Mary off at the airport and hugs her goodbye, in the background there are two men walking towards them. The camera changes to the angle behind Mary then behind Lloyd and then back to the side. When it returns to the side view the two men are farther away but still walking toward them. (00:07:25)
Revealing mistake: When the air bag inflates at the airport and Lloyd is wrestling with it for a split second he pulls it back and you can see it is not attached to the steering wheel. (00:08:40)
Factual error: When the airbag blows in Lloyd's limousine, it stays inflated - it should instantly deflate. (00:08:40)
Revealing mistake: When Lloyd drives into the back of a car at the airport his air bag inflates and it looks it is made out of thin rubber translucent material. That is not what real air bags are made of. (00:08:40)
Continuity mistake: Speaking of the airbag mistake, how about the fact that the hub of the steering wheel in the Cadillac Limo was small, and could no way have an air bag behind it? (00:08:40)
Continuity mistake: When Mary leaves her briefcase on the airport floor, Jim Carrey is seen running and sliding to the briefcase. In the scene directly preceding that, he is nowhere to be seen, yet instantly he is teleported within 20 feet of the briefcase. (00:09:35)
Continuity mistake: Right after Lloyd runs into the jetway at the airport, the guy who witnesses his fall moves to the window to watch. He is grinning from ear to ear in his reflection, but immediately has a 'that had to hurt' look in the next shot. (00:10:15)
Continuity mistake: In the scene at Harry and Lloyd's apartment, one of them opens a beer and throws the cap on the floor. In different shots the beer cap moves from place to place on the floor. (00:12:06)
Continuity mistake: When Jim Carrey and Jeff Daniels are in the restaurant, just before they encounter Seabass and right after they call the waitress "Flo", Jeff's coke glass is on his right side. The next shot shows it on his left, then his right, then his left again, without him touching it. (00:21:56)
Continuity mistake: In the scene at the truck stop, just before C-Bass comes over to Jim Carrey and Jeff Daniel's table, the same teenage boy walks by the window twice with his girlfriend. Also, the "Aspen" hotel is really The Stanley Hotel in Estes Park, Colorado. The Stanley is the hotel Stephen King based The Shining on. (00:22:00)
Continuity mistake: When Lloyd and Harry are in the restaurant notice Lloyd's fork. In the side shot there is no fork, but when it changes to a front shot the fork appears. This happens several times throughout the scene. (00:22:00)
Continuity mistake: When Harry and Lloyd are at the truck stop, there is a man sitting behind Lloyd. In the shots of Harry only, he is leaning towards the window, in the shots of Lloyd only, he is sitting up straight. (00:22:06)
Continuity mistake: When Lloyd tells Harry to throw some salt over his right shoulder, he puts the salt shaker next to Harry's burger and fries. The next shot shows the salt shaker behind the basket of Harry's food. (00:22:49)
Continuity mistake: When Lloyd is peeing in the beer bottles, he hands them to Harry... it shows him holding the bottles... next shot, he isn't holding them, and the shot after that, he is holding them again. (00:26:00)
Suggested correction: In the shot where he is "not holding them", they are simply out of the frame. He was actually holding them all along.
Continuity mistake: When they have left the cafe without paying, and Lloyd has to pee, Harry's hair is blowing in one shot because the window is down and in the next shot the window is up and his hair is not blowing. This goes back and forth for the duration of the scene. (00:26:00)
Continuity mistake: When the policeman is driving next to Harry and Lloyd's van telling them to pull over after their encounter with Sea Bass, the lines on the road are single broken lines. After they pull over, the police man walks over to the van and the road lines are double solid. (00:27:45)
