Continuity mistake: When the brunette is in the shower and that boy shows up he is wearing brown pants, but when you see the clothes lying on the carpet while they are in bed together, the pants are blue jeans.
Continuity mistake: When Julie and Stacy are getting ready for the party, Stacy is helping Julie with the buttons on her sleeves. Stacy buttons the right sleeve, then the left in one shot, and in the next shot Stacy is buttoning Julie's right sleeve again.
Continuity mistake: In the sleepover scene in Suzi's bedroom, the girls are dancing, and Stacey is wearing plain, light blue underwear. As they cross into Suzi's mother's bedroom, Stacy's underwear change into striped underwear.
Audio problem: In the scene where Skip delivered groceries to Suzy's house, he and Beth are standing face to face flirting by the pool. At one point while they are talking, you plainly hear a door opening, as well as a few footsteps. No one else was supposedly home at that time.
Factual error: When they drive away at the end they say they are going to the Valley Sheridan, but when the camera pans out they are really going in the opposite direction towards Santa Monica
