A nameless member

Revealing mistake: On the day the house is being emptied, after Bluto finishes the Jack Daniel's and tosses the bottle, there are no Jack Daniel's labels on it. (01:07:35)

Deliberate mistake: When Cochran sabotages the Jet Ranger helicopter by loosening the nut on the bolt securing the linear actuator governor, the bolt is inserted in the wrong direction. The bolt should have been heads up to prevent it from falling out as it did causing the helicopter to crash. Moreover, the linear actuator is on the opposite of the engine from where Cochran disconnected it. (00:38:05)

William Bergquist

Continuity mistake: When Roy Scheider's partner is killed, he is run over by a car. After the car runs him over, his body rolls and you can see his arms swinging freely even though his hands were bound by the plastic ties. Later when you see his body, his hands are bound again. (01:10:30)

Continuity mistake: When the Fraternity house is being taken down, the Greek letters switch places. (01:06:05 - 01:06:55)

Continuity mistake: During the Delta Rush Party, Pinto (then just a pledge) got a beer. Notice that, as the scene changes camera angles, the heads on the beers go up, down, and up again. (00:07:30)

Continuity mistake: In the scene where Pinto is making out with the Mayor's daughter, as she sits up on him so she can unhook her bra, he starts to slide his hands under her bra right before she passes out and falls over. As she is falling he pulls the tissue paper out which hangs like streamers from his hands to elbows. After a quick shot to show her on the bed, there is a shot of Pinto now holding the tissue in little tiny balls in each hand. (00:58:05)

Continuity mistake: During the classroom scene, Donald Sutherland writes the word "Satan" on the board. In the first shot, the "t" in Satan in directly over the crease on the chalkboard. In the next shot, it is clearly on one side of the crease. (00:18:00)

Continuity mistake: During the parade, Flounder dumps the bucket of marbles towards the camera, and they are all clear glass marbles. When the ROTC members slip and fall on them, the marbles are red, blue and yellow. (01:38:25)

Continuity mistake: When Stork and his associate step conspicuously onto the curb to watch the parade the pompom's yellow tassels face front. When the man behind them says, "Excuse me, my kid can't see," the purple tassels face front. (01:33:05)

Visible crew/equipment: In the scene just prior to the food fight, as John Belushi goes through the cafeteria line putting the food on his tray (which moves frequently), note the cameraman's feet in the mirror over the food following him. (00:33:30)

Factual error: In the scene where Pinto buys/shoplifts food from the grocery store and meets the Mayor's daughter, the cash register has an LCD display. A little too futuristic for a flick set in '62. (00:47:30)

Revealing mistake: When Bluto is watching the sorority girls have their pillow fight and he falls down with the ladder, you can see him land on a grass mat that is cut into the lawn. It's funny because you can see the grass push in. (00:40:00)

Continuity mistake: When one of the Delta Frat Guys is drinking beer in the frat, in his close up he is holding a mug by the handle, in the reverse shot he is not holding the handle. (00:07:30)

Continuity mistake: In the cafeteria "I'm a zit" scene, Bluto picks up the mashed potatoes with his right hand, but the very next shot shows him placing it in his mouth with his left hand. (00:34:50)

Continuity mistake: In the scene where Otter and Boon are hitting golf balls near the ROTC drills, Otter puts down the golf bag he is carrying and draws a club. The camera moves to the ROTC trainees, and when it comes back to the golfers, the bag is back on Otter's shoulder and there is no club out of the bag. (00:20:10)

Continuity mistake: Before the hearing, Katy and Boone are talking at the bottom (half) of a stairwell when Otter comes down with a briefcase in his right hand and he puts his left hand on Boone's shoulder. In the next shot the briefcase is now in his left hand with his right hand on Boone. (01:00:55)

Continuity mistake: In the cafeteria, Bloto puts stuff on his tray. Before the cut his bunch of bananas are on the side of the tray. After the cut the bunch is on the other side. (00:33:05)

Continuity mistake: When Kitty is scrubbing the deck with Caroline and Captain Ron turns up with the video recorder, Kitty is in the midst of putting on her yellow cleaning gloves and the scene immediately shows Captain Ron filming Kitty's behind while she is wiping her hands on the back of her jean shorts and Kitty has no yellow gloves on. (00:41:15)

Continuity mistake: When Lane is about to kill himself with carbon monoxide fumes from the car in the garage, he passes out and backs up out the garage door..if you look close you can see a conscious stunt man sitting up as the car goes backwards. (00:39:35)

Continuity mistake: When the "I LUV YOU" picture is viewed in Nordberg's hospital room, the photo has a vertical/portrait orientation. When Frank shows the picture to Jane, the photo has a horizontal/landscape orientation. (00:12:50 - 00:38:25)
