Porky's (1982) - 6 mistakes

Continuity: Coach Brakett (Boyd Gaines) finally convinces the young gym teacher, Honeywell (Kim Cattrall), to go with him to the boys' locker room. Once they are up there he disrobes her and gets on top of her. When they cut to a close-up, you can tell that he has longer hair than just two seconds before.

Continuity: When Brian Schwartz drives away in his sports car, you can hear him shift 4 times. When they show a shot of his car go by, he is only going about 5 miles per hour.

Continuity: When Timmy cleans out his gym locker, he took only two items from the locker, stuffing them in the basket haphazardly. In the next shot when he is at the counter returning them to the phys ed coach, the basket is now full of at least six different items, all neatly folded.

Continuity: When they guys are fleeing the house in the woods, in the long shot Meat is in front of Mickey, but in the close up Mickey is in front of Meat.

Factual error: This movie was set in 1954, but in numerous street scenes more modern "cobrahead" streetlight fixtures are seen. That type of streetlight was first introduced in 1957.

Continuity: When Porky pulls the lever we see the guys fall into the river. Then from another shot we see them get out, and go round to argue with Porky, but they are now dry. Impossible considering the few seconds time difference.
