Continuity mistake: When Lloyd is trying on tuxedos, the shot from the back of Harry's head you see a short cigar in his mouth. In the next shot from behind (when he stands up), the cigar gets bigger. (01:04:40)
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)
Continuity mistake: When Mary and Harry are talking about the "Bull-Shit" there is a shot of Mary close up where she is laughing and smiling. Look behind her and you will see a woman in a black and gold glittery dress walk past. Then when the shot changes to both Mary and Harry together the woman is instantly 3 or 4 feet in front of where she was and seems to be engaged in a conversation with someone else already - instantly. (01:06:50)
Continuity mistake: At the ball Helen and Harry are talking and in the background you can see Lloyd and his hat is on the bar. A second later he shows off his butt and he is holding his hat. (01:10:29)
Continuity mistake: There is a scene just after Lloyd meets Beth in the bar when Mary is skiing along and looks around for Harry who is still stuck on the ski lift. The shot is comprised of a long shot of her skiing to a grey marker and then a close up of her stopping and looking around. It is obvious in the shot when she comes up to the marker that the woman on the skis has much darker hair than Mary and is her "ski double". (01:13:20)
Continuity mistake: When Harry has his tongue stuck to the chairlift, there is frost on the pole when he licks it. Later, when he asks the kids for a cup of warm water, there is none. Then when Mary removes his tongue, the frost is back. (01:14:35)
Continuity mistake: When Harry and Mary go out on the date to the ski resort, when they get into a snowball fight, the camera shows Harry, and it's snowing, but when they show Mary (who is supposed to be right beside him) it is not snowing. It keeps doing that, when it shows Harry it's snowing, and Mary it is not (or vice versa). (01:17:50)
Continuity mistake: When Harry and Mary go out on the date to the ski resort, they get into a snowball fight. When Harry is shoving her face in the snow, the first time it shows Mary she is facing one way, but when they show her again she is facing a different way. In addition to this before the camera cuts to a different angle on Harry you can see Mary's nose is bleeding immediately after she stands up. The camera then cuts to a different angle and it isn't. (01:18:21)
Continuity mistake: When Lloyd asks if the bartender knows Mary, he originally grabs the bartender with the left hand. But in the next shot he lets go of him with his right hand. (01:19:18)
Continuity mistake: In the scene where Lloyd is making drinks for him and Harry, there is a half full bottle with something that looks like whisky in it. Then the cameras changes angle to Harry for 2 seconds, and then again back to Lloyd, but suddenly there isn't half as much "whisky" in the bottle as before. It is impossible that Lloyd could have poured so much "whisky" into the glasses in only 2 seconds. (01:19:40)
Continuity mistake: When Lloyd tackles Mary on the hotel stairs, she is wearing black pantyhose. By the time they get to the hotel room, she has miraculously changed into grey tights. (01:28:45)
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: After Mary removes Harry's tongue from the pole her ski out fit is blue when before that it was black.
Continuity mistake: When Harry and Lloyd are leaving Providence, in the first shot of the highway we see them driving on Route 146. In the next shot showing the Highway, they are driving on Route 95 South. There is no way they can be driving on both highways at the same time, and, if they could, they would be driving in opposite directions at the same time.
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.
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.
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).
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.
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.
