• As a result of the film shooting in the spring, all of the trees seen in the film are in full bloom.

• Tina’s hair changes styles throughout the night of the party. When she’s getting ready, she places it in a high bun. When she enters the barn later on, it’s in a pony tail; later in the barn, it’s completely down, before changing once more during the car chase.

• Michael wouldn’t have been allowed to keep his mask on in prison.
