Continuity mistake: When Gun is having lunch with the Sensei, Gun picks up a bowl of noodles as well as two chopsticks. At first, the two chopsticks are facing outwards. But in the next shot, the two chopsticks are facing inwards toward the bowl. (00:03:53)
Continuity mistake: When John Candy is woken up by his wife after getting drunk with Scully, he has a hoop earring in his right ear. Later during the regatta, the earring appears in his left.
Continuity mistake: Madeleine's dress sleeves are pulled back when she's first on campus with Grinshaw. Then, when she meets Danny, they're suddenly down at full length.
Continuity mistake: When Mickey is being interviewed for the yearbook, watch out for students that walk in his opposite direction. There are obvious recycled extras appearing in multiple shots coming from the same direction, such as the blonde with checkered top paired up with a guy in a blue shirt. (00:09:00)
Continuity mistake: During the scene when Andrea's talking about suing the club, the amount of papers in her hands change from 4 to 5 in between shots. (00:44:20 - 00:45:21)
Continuity mistake: Right after Lucy buys her pictures, she walks on the plaza and takes off her coat, carrying it on her arm. When she starts fainting, George catches her and starts carrying her. Both of her arms are in clear sight and the coat is nowhere to be seen. The shot changes, and then her coat is again wrapped around her right arm, squished between their bodies.
Continuity mistake: When Lloyd wheels out his camera and begins filming, you can see that it's a Betamax. When the cute little kid holds up the video tape produced by that camera, it's a VHS tape. (You can tell because it fits neatly inside the box. Beta tapes were entirely different dimensions from VHS and a Betamax wouldn't fit in a VHS box.)
