Animal House (1978)

Continuity mistake: When the authorities and moving crews are clearing all of the junk out of Delta House, we see a workman with a hammer removing the fraternity symbols from the house's upstairs railing. However, the symbols are not in the correct order: They read "Delta Chi Tau," and the workman is removing the "Tau" from the end. Moments later, we see the workman still removing the fraternity symbols, but now they are in the correct order, "Delta Tau Chi," and he is removing the "Tau" again, but removing it from the center.

Charles Austin Miller

Continuity mistake: When the Dean is on the phone in the middle of the night, his drunk wife gets her feet tangled in the phone cord, then falls off the bed, pulling the receiver off the hook. In the next shot showing her giggling on the floor, the phone cord is no longer visible.

Continuity mistake: At the end of the parade, Neidermeyer has a rifle in his hand as Flounder approaches him with a seltzer bottle calling his name. Neidermeyer lifts the flap of his pocket to reveal one round for his weapon. He loads it in to the chamber and fires. He then reaches in to his pocket a second time, loads and fires, but the first shot showed only one round in the pocket.

Continuity mistake: While the chaos during the parade scene near the end of the movie is happening, look at the store windows during some of the shots of the people running up and down the streets. Some of the light up signs and other posted items on the windows, appear to be reversed as if the same shots were used several times, just reversed time from time to make it appear that people were running in both directions of the street.

Russell80

Continuity mistake: At the start of the party, the character collecting the coats throws them on the floor in front of the door. Yet when Kent Dorfman and his date enters the house, they are obviously not there, as the door opens easily and they do not have to step over them when they enter.
