Dumb and Dumber (1994) - 77 mistakes

Continuity: 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.

Continuity: 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.

Continuity: 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.

Visible crew/equipment: When Lloyd is daydreaming about Mary as the doors to Mary's house open and Lloyd picks up Mary. He lifts up her skirt to show a little flesh, in the background you can see the feet of two crew members laying on the ground holding the doors open.

Audio problem: When Harry and Lloyd pick up the hitchhiking natives, when they were playing the mockingbird song, the guitar was playing but his hands weren't moving at all.

Continuity: 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.

Continuity: 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).

Visible crew/equipment: When Harry and Lloyd are leaving Providence, there is a hand moving the curtain behind Harry.

Continuity: 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: After leaving the diner, Lloyd & Harry are pulled over by a motorcyle cop (Harland Williams). As the cop notices the beer bottles on the floor of the van, you'll notice his hair has a curl hanging over his forehead. Right before he takes a drink of one of the bottles, the curl is gone. It cuts to Lloyd & Harry trying for a brief second , and when it cuts back to the cop saying "You'd shut your mouth if you knew what was good for ya," the curl is back.

Continuity: In the side shot in which Lloyd tells Harry to toss some salt over his right shoulder, Harry is holding his straws at an angle off the table. Then it switches to a front shot of Harry, and he is now holding his straws vertically on the table.

Continuity: 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: 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).

Other: 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).

Revealing: When Harry and Lloyd are at the restaurant with the kidnapper they give him the hot peppers. Then he falls to the floor and Lloyd is trying to give him C.P.R. If you look in the background you can see the waitress laughing in the first few shots.

Continuity: 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.

Factual error: Why don't the "beer" bottles on the floor of the van fall over? When the cop stops Harry and Lloyd the bottles are all standing perfectly upright and there has not been any spillage on the floor. Bear in mind that before this they had been driving on the verge and stopping and swaying when the cop tells them to pull over. And Harry is only holding 3, and yet 6 appear on the floor.

Visible crew/equipment: On the DVD when Harry is in the bathroom (from the ex-lax) as he sits on the toilet if you look on the floor you can clearly see the dolly track for the camera.

Visible crew/equipment: I think you can only see this in the DVD version, but when the guys are at the important benefit with the owls and Lloyd pops the cork off the wine bottle which kills one of the owls, in the part where you see behind the cork and it is spinning you can see the stick which holds it (the cork) up.

Revealing: The Aspen lift operators are wearing Copper Mountain uniforms. Copper Mountain is in Colorado, but it is over two hours away from Aspen.

Continuity: When Lloyd states that the map says they've only drove a quarter of an inch, you will see a creek with a unusual tree growing around it. You see the same creek and tree when Harry and Lloyd pick up the "gas man".

Continuity: 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.

Revealing: 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.

Continuity: When Harry sits down on the toilet and lifts up his legs, his eyes are closed, and they remain closed until the very end of that particular shot. Then, when it switches to the front shot of Harry a few second later, his eyes are open, right from the very beginning of that shot. And if you look closely at that shot change, you don't see Harry do the action of opening his eyes - they just change instantly between the shots.

Continuity: 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.

Plot hole: After Lloyd's encounter with Seabass in the restroom at the gas station, we see the FBI waiting for Harry and Lloyd at the Colorado border (we even see a front shot of the road and mileage sign), and there is no town in sight. Then we see Harry and Lloyd 3 miles from the border, driving toward it, where the FBI are waiting. Then we see Lloyd coming out of a market in a little town, after which, upon leaving the town, he drives in the wrong direction. How did they suddenly come upon this little town, especially when they were only 3 miles from the border? Did they turn around, or what happened? (In the unrated version, the van scene 3 miles from the border is extended, and it seems that they would have reached the border, and the FBI, by now.) The whole scene here is pretty confusing.

Continuity: When Lloyd drops Mary off at the airport, the interior of the car is different once Lloyd gets back in.

Continuity: 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.

Revealing: 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.

Continuity: 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.

Continuity: 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: 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.

Continuity: In the Unrated Version DVD, in the van sequence after Lloyd's second encounter with Seabass in the restroom, Harry says that he will stop talking about Lloyd's encounter with Seabass. Lloyd turns his head and looks over at Harry. Then it switches to a close-up on Lloyd from the other side, and we see him repeat the same action of turning his head and looking at Harry, this time more sharply.

Continuity: Right before the officer on the bike calls Lloyd a "pumpkin-pie-haircut freak", Lloyd is sitting back, straight faced, then after the officer says it Lloyd is leaning forward smiling.

Revealing: When Harry and Lloyd are reading the newspaper about the International Preservation Society, the exact same paragraphs are repeated many times throughout the paper.

Revealing: In the dream sequence where Jim Carrey is being beaten backwards by the chef, there is a shot of Mary as she watches. As they move past, watch her hand and eyes move down to the table; I think she knocked her glass or something on the table and was trying to correct it. Whatever it was, she momentarily loses complete interest in the fight in front of her.

Continuity: 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.

Continuity: In the scene when Harry stops and says to Lloyd,"look at the butt on that", there is a man with a blue coat that walks behind them into a store. When Harry and Lloyd turn around to keep walking, you can see the blue coat man entering the store once again. You may have to freeze frame it to see the man the second time.

Continuity: 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.

Revealing: At the Swanson's ski-lodge, there is snow on the rail of the balcony, but the mountains in the background are completely snowless.

Continuity: After Mary removes Harry's tongue from the pole her ski out fit is blue when before that it was black.

Audio problem: In the very beginning Lloyd opens a bottle of beer in their apartment. When the cap falls on the floor it makes a clinking sound as if it landed on tile, however, their floor is carpeted.

Other: When Lloyd is in the bar and he has just said "Everything has to be perfect", he gives a big sigh and the camera is facing his front. Then the camera is facing the barman and he gives the same sigh. You can see from how his face changes from smiling to a frown.

Continuity: 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.

Revealing: 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.

Audio problem: On the subtitles for the UK "Uncut" DVD (I'm not sure if this applies to other "Unrated/Uncut" DVDs), the subtitles mix up the character names during one shot. As Lloyd goes in the wrong direction, the film cuts to a shot from behind the pair. Harry says that he "expected the Rocky mountains to be a little rockier than this." The subtitles incorrectly state that this line was said by Lloyd. Lloyd's response that "John Denver is full of shit" is also incorrectly attributed to the wrong character; the subtitles say Harry said the line instead of Lloyd.

Continuity: 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: In the shot early in the movie when Lloyd gets his wallet trapped in the newspaper machine it shows his wallet, however in the very next shot you can see that his wallet is not there.

Continuity: Before Harry and Lloyd begin their conversation about gambling, they seem to be driving by a lake; but from the inside, they're driving by a town.

Continuity: 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".

Continuity: 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.

Continuity: 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.

Continuity: 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.

Revealing: 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: When Lloyd is swinging his arms in the van, pretending to be 'running at an incredible rate', they are driving through a countryside with nothing but open plains. In the next shot, when Lloyd says 'we're really doing it though aren't we buddy?', look outside the passenger window. They are suddenly driving past houses in a residential area.

Continuity: 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.

Continuity: 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.

Revealing: During the tongue scene, when Mary is pulling Harry's tongue off the ski lift, you can see Harry's real tongue right under the fake stretchy one.

Visible crew/equipment: When Harry gets pulled over the officer's sunglasses reflect the camera man.

Continuity: When Harry delivers the dogs, there is no carpet on the floor in the car. But when the indians are sitting in the car suddenly there is a carpet on the floor.

Continuity: 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.

Continuity: 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.

Continuity: 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.

Other: When Jim Carrey races Mary up the stairs at the hotel, he falls down on the stairs. He attempts to grab her by the ankle to stop her. He misses grabbing her ankle (by mistake)but she falls down anyway.

Revealing: 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.

Revealing: After Lloyd drops Mary off at the airport, he starts the limousine and puts the car into reverse, but the car moves forward.

Continuity: 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.

Continuity: 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.

Revealing: 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.

Continuity: 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?

Factual error: Harry's tongue gets stuck to the chairlift, and stays stuck, even though it's not cold enough to see anyone's breath, or for everyone to need their jackets zipped-up.

Continuity: 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.

Revealing: When Harry and Mary are making the snowman, there are three pre-formed holes where Mary puts the charcoal and carrot (the eyes and nose, not the twig and berries, but maybe them too, I can't tell for sure).

Continuity: 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.

Other: You have to know Colorado to get this one, but the two guys are on a trip to Aspen to return the suitcase to the woman. But when they finally arrive, they are not actually in Aspen like you are supposed to assume they are. The whole Aspen scenario actually takes place in Breckenridge ski resort.

Continuity: When Mary's family is shown in their home in Aspen. Mary is sitting on the couch with hot chocolate in hand, and is shown with her right leg crossed over her left. However, when Nicholas walks in, magically Mary's left leg is crossed over her right.

Continuity: When Lloyd has drove the dog car the wrong way across the plains, and Harry yells at Lloyd and says that he is walking home, the camera views Lloyd calling Harry Mr. Perfect for about 8 seconds and then shows a far view of Harry walking about 60 feet away from Lloyd. I don't think he can walk that fast in 8 seconds.
