Continuity mistake: When Harry and Lloyd go to the preservation dinner, Nicholas is standing by the front door. A few minutes later, he is up on the stage starting the presentation and introducing Mr. Swanson. Then instantly, he is back by the front door talking to his comrade. There is no way Nicholas could have done what he did in so little time - he doesn't look out of breath -- and without being seen.
Revealing mistake: The Asian man at the airport terminal is struggling very hard not to laugh at Jim Carrey's antics, as seen from his reflection in the glass.
Continuity mistake: During the snow owl benefit, Mr. Swanson (Mary's dad) is introduced. The next shot is from behind the stage facing out to the crowd and you see Mary's stepmom (Teri Garr) raise her arm in the air as if to "present" Mr. Swanson. The very next shot is from the audience perspective facing the stage, and Teri's arm is at her side, and she raises it up again to present him. (01:06:44)
Revealing mistake: When Jim Carrey and Jeff Daniels are fighting at the park over the briefcase, the snow is obviously foam or some other material. The same thing also happens right when they get to Aspen and walking from the street on to the curb, the snow moves. (00:59:24)
Revealing mistake: When Harry is talking to the lady at the gas station, and his legs catch fire, you can see the burn gel on his pants.
Other mistake: In the brief scene in which Nicholas Andre and J.P. Shay are talking about the killing of the owl at the preservation society ball, if you look very closely out the very bottom of the window, at the very end of the short scene (right after Andre says, "Their guys aren't just anybody, they're good"), you can catch a brief glimpse of part of the box containing the victim who is trying to escape (this box was completely excluded from the film).
Continuity mistake: Towards the beginning of the movie at Lloyd and Harry's apartment during the scene when Harry is behind the couch yelling at Lloyd about going to Aspen you can see an empty beer bottle, when Harry walks around the Couch again the beer bottle has moved.
Other mistake: When Lloyd gear shifts the limousine at the airport he only moves it down one notch, which would be reverse. The limo still moves forward.
Revealing mistake: In the beginning of the film, Harry reaches for his radio after getting a call. The radio is not powered. You can see the display doesn't light up.
Continuity mistake: After Harry and Lloyd start gagging over the atomic peppers, we see a brief shot in which everyone else in the restaurant looks at them (and the waitress suddenly appears in that shot as well). But in very the next shot (back to Harry and Lloyd, still gagging), nobody is looking at them (and the waitress, who was there just a moment ago, disappears).
Visible crew/equipment: When they are riding the mini-bike as "Where I Find My Heaven" is playing, the camera goes towards the sky. Look to the far left, you see a small looking man in blue overhauls.
Continuity mistake: When the "gas man" falls to the floor due to the atomic peppers that Harry and Lloyd sneaked into his burger, Harry and Lloyd laugh at him, and Lloyd even points at him. Then he stops pointing at him and looks at Harry. But only a moment later, in the very beginning of the next shot (a close-up of Harry and Lloyd), Lloyd is instantly pointing again.
Continuity mistake: When Harry and Lloyd start singing "Mockingbird," we see a front shot of the "gas man" getting annoyed and gritting his teeth. Then it switches to a side shot, and his annoyed expression is now different, instantly.
Visible crew/equipment: When Jim Carrey slides in the airport to pick up the briefcase, he stops at a strip of red tape which marks the place where he should stand up.
Continuity mistake: When Nicholas Andre shoots Harry twice in the chest, the gun is empty after the two shots. The camera then moves to Harry getting up and shooting back. When the camera returns to Nicholas, the gun is not empty. (01:32:25)
Continuity mistake: When Lloyd drops Mary off at the airport, the interior of the car is different once Lloyd gets back in.
Suggested correction: The interior is the same, but looks different due to the direct sunlight in the first shot (blue instead of black). The only difference is the steering wheel, which is not contain the airbag on the way to the airport, but is totally different when Lloyd is back in the car and is driving right before the impact.
Revealing mistake: When Harry and Lloyd are reading the newspaper about the International Preservation Society, the exact same paragraphs are repeated many times throughout the paper.
Continuity mistake: Early in the movie when Lloyd gets his wallet trapped in the newspaper machine, it shows his wallet, however in the very next shot his wallet is not there.
Revealing mistake: When Lloyd comes back for Harry on the scooter, it has two small training wheels on the back. They disappear in the montage of the ride to Aspen and reappear when they pull into town.
Continuity mistake: Harry is wearing the bullet proof vest and gets shot. Yet there's no damage to it when he opens his shirt.
