Friday the 13th Part 3: 3D (1982) - 93 mistakes

Continuity: After Edna yells through the window at Harold for knocking down the clothesline pole, she slams the window shut and the end of the curtain gets trapped under the window. Then the scene cuts to show Edna from the inside, and look at the curtains from this shot. They are now hanging straight down, just like it should be and aren't trapped.

Continuity: When Edna keeps looking out the window, to see Jason take the clothes from her clothes line, the curtains keep changing position, and from shots outside the left curtain isn't visible but from inside, it covers a portion of the window.

Continuity: When Harold feeds the fish, in wideshots there is a note next to the fishbowl which reads "Say Hi to..." However in the closeups of the fishbowl, the note has gone, and should be visible.

Continuity: Between shots, as Harold spit’s the fish food out, the position of the figurine fisherman’s wooden rod changes.

Continuity: When Harold finds the rabbit in his store, it is in a crate of vegetables. Between shots, the vegetables which are in all of the crates change; for example some of the broccoli stems turn into lettuces in the next shot.

Continuity: Harold puts the fishfood bottle down on the counter with no lid on it. However when he's eating the doughnut you can see the fishfood bottle is now on the till, with it's lid on.

Revealing: When the snake leaps out of the cage, you can see a dodgy looking fake snake attached to a wire spring.

Continuity: When Harold is at the toilet you can see a shelf behind him with a fire extinguisher and a piece of cloth on it. Also the shelf is by his waist level. A moment later the extinguisher has changed, the piece of cloth is gone, the shelf is by his shoulder level and a clock has suddenly appeared on the wall. It is obvious this is a change of stage scenery.

Continuity: When Harold is on the toilet, the toilet roll sits on the centre of the shelf behind him. Moments later when he looking around, it is right by the edge of the shelf.

Continuity: When Harold is stabbed with the butchers knife, blood runs all down his shirt. Then when it cuts to a closer view, blood is just around the knife.

Visible crew/equipment: When the kids stop and gets out of the car you can see the microphone reflected on the car.

Continuity: At the start in the van, the girl you see smoking dope hands over her cigarette to the other kid. She uses her index finger and her thumb with the cigarette facing downwards, but in the next shot she has got it between her index finger and middle finger and it is facing upwards.

Continuity: When the kids stop for the police cars who rush by we get to look out the back window of the car. You can see a car and a road sign there. These two wasn't there when they pulled over.

Continuity: Right before Chris stops the van to avoid hitting Abel you can see that none of the others are in the back of the van.

Continuity: When the kids get out of the van and run over to Abel, who is laying in the road, you can see Chuck and Andy standing next to see other (you can see their legs.) In the very next shot, Vera is standing in between them.

Continuity: When they arrive at the lake and get out of the van, the long shot from the passengers' side shows Chris getting out and slamming her door, but then the next shot from the driver's side shows her getting out and slamming the door again.

Visible crew/equipment: When the gang get out of the van when they arrive at the camp, Chris tells them that she is going to take a look around. She then opens the rear door of the van and you can faintly see a reflection of a boom mic.

Continuity: When Chris first enters the cabin and talks with Rick, and also in later scenes throughout the movie, the hat hanging on the pegboard beside the cabin door changes position a few times between shots.
