* AbilityOverAppearance: Judy was intended to be a blonde, to contrast against Angela's brown hair. But Karen Fields played the AlphaBitch so well that the character became brunette.
* CastTheExpert: The paramedics carrying away the injured Artie were locals. Their squad is seen written on their jackets.
* ColbertBump: The film was always regarded as a CultClassic, but it did get a minor boost in popularity after being featured on ''WesternAnimation/RobotChicken''. It was even [[LampshadeHanging lampshaded]]:
-->'''Camper:''' Oh my God! [[spoiler:Angela's the killer and she was really a boy!]]\\
'''Robert Hiltzik:''' Oh my God! Somebody remembered this movie and wrote a comedy sketch about it!
* CreatorBacklash: The director later said he regretted having [[spoiler: Angela kill the kids who threw sand on her]]. He wanted every victim in the movie to be an AssholeVictim and later decided that this was a bit DisproportionateRetribution.
* CrosscastRole: [[spoiler: Felissa Rose as Peter, raised as Angela]].
* DawsonCasting: Mostly averted with the cast. Katherine Kamhi was borderline as Meg; she was nineteen.
* EnforcedMethodActing: The man who stood in for [[spoiler: Felissa Rose]] in the final scene had to be drunk before he could properly film it.
* RealLifeRelative: A lot of the cast and crew's relatives appeared as the campers getting off the bus near the beginning of the film.
* RealLifeWritesThePlot: Felissa Rose's mother protested about a couple of things that influenced the shooting process - and resulted in some additional {{Foreshadowing}} of the twist. [[spoiler: She did not want her daughter to be the killer, as she was too young. So the male Jonathan Tiersten acted as her double, and stood in for her in most of the killing scenes. It's him wearing a wig in the scenes where Kenny and Judy are killed. His hands are used in most of the shots of only Angela's hands, again to hide the killer's identity]].
* WhatCouldHaveBeen:
** [[{{Series/ThirtyRock}} Jane Krakowski]] almost played Judy, but had problems with [[CruelAndUnusualDeath the way she would die.]]
** A shot of Judy [[spoiler: after she's killed with the curling iron]] was cut by the censors for being far too graphic.
** [[spoiler: Ricky originally died when Mel beat him at the end.]] Only during shooting did Robert Hiltzik decide to film [[spoiler: Ricky showing signs of survival.]]
** Felissa Rose was originally going to do the end scene [[spoiler: wearing a prosthetic penis]]. They eventually decided to achieve the shot with [[spoiler: a boy wearing a cast of Felissa's face]].
