Visible crew/equipment: When Pee Wee is chaining up his beloved bike you can see the long chain coming up through the bottom of the bike box. Full screen version only. (00:13:40)
Visible crew/equipment: When Mrs. Peacock turns on the cellar lights, a piece of lighting equipment is visible to the left of the screen. (00:47:45)
Continuity mistake: During the jail breakout, when Jake tries to open the ORV's door, in the shot facing Francis he is holding the gun in his left hand as he tries to open the door for his brother with his right hand. In the next shot facing Jake just before shouts, "I don't have the handle, open the lock!" Francis's gloved left hand is empty, and next shot, the gun can be seen in his right hand. (00:01:45)
Continuity mistake: When Marty chases after Biff on the borrowed 'skateboard', Marty is wearing a dark grey belt and a red/blue print shirt under his red/beige jacket. However, when Marty is hanging on to the front of Biff's car as they turn a corner (and in another shot), Marty (stunt double) is wearing a light brown belt and solid tan shirt. (01:07:00)
Visible crew/equipment: Michael J. Fox is dancing on top of a bus as the Teen Wolf. The camera swings just a little too far toward the back of the bus and a police car that is escorting the camera car and bus is seen in the rear with its red lights going.
Continuity mistake: Near the end of the movie, when Parker and Hunt are on the bus going to the contest, you'll see that Parker's hair is in waves. But when she arrives at the studio, her hair is VERY curly. Its not likely that she had time to change her hairstyle THAT drastically if she was pressed for time as she very clearly was.
Factual error: A native French speaker like Monique would never mistake the word 'testicle' for 'tentacle'. The French word for 'testicle' is 'testicule' and the word for 'tentacle' is 'tentacules' - both are pronounced almost identically to the English form. She'd have to confuse the two words in French, and not even a non-English speaking French person would make a mistake like that. Monique's English is very good. She'd be perfectly aware of what she was saying.,.
Revealing mistake: When Charley stabs Dandridge in the hand with his pencil, he stabs the hand holding him by the neck. The depth of the wound on Dandridge's hand reveals that the pencil should have stabbed Charlie in his neck and given him a severe wound, if not kill him.
Continuity mistake: After Molly Ringwald does her trick, she puts the lipstick away twice. It has a shot of her putting it away from the front and then another one from the back.
Other mistake: When Chevy chase is being filmed cheating on the exam, all the video cameras are on the sidewalls near the roof. But later when they view the footage, the last shot of Chevy copying the answers is from the floor level where no camera was seen in any previous shots. Also what was a floor level camera going to film anyway...everyone's feet?

Visible crew/equipment: In the scene where Burt and Spider take the cop car to go get help, after they back up from the group of zombies in the street. You can see a cameraman in the front passengers seat holding a camera with a blinking red light on his shoulder as they drive away.
Continuity mistake: When Fletch and Stanwyk first meet and Stanwyk asks Fletch to come to his home and hear his proposal, Stanwyk is wearing a suit/tie on top but is wearing jeans on the bottom. In the next wide shot as they leave the beach, and again in the next scene as they arrive at Stanwyk's house, he is wearing suit pants. (00:04:50)
Suggested correction: Stanwyck is never wearing jeans in any of the scenes, he's always wearing matching suit pants.
Plot hole: When Diana turns up at her director friend's house she finds it crawling with cops as his girlfriend Christie has been murdered and the house is now a crime scene. She explains she lent Christie a coat and is there to pick it up - and a cop helpfully finds it on the floor and hands it to her. Are we to believe that a homicide policeman will hand over an artifact from a murder scene to an unidentified woman without making any attempt to confirm her identity, or even if the coat is even hers!? They don't even ask.
Continuity mistake: Towards the end of the movie at the prom, Terry finally shows Rick that she's really a female. She exposes her breasts. Now obviously she's not wearing a bra. But in the next scene you can see she's wearing a lace one.
Other mistake: When the fake TV ads for the Stuff are shown, the container states "1 Pint (.474ml)". 0.474ml is about an eyedropper drip of liquid. The decimal point shouldn't have been there.
