13 Totally WTF Horror Movie Plot Twists
2. "Angela" Is Actually Peter (And The Killer) - Sleepaway Camp
Could anything really take the #1 spot away from the infamous 1983 cult classic Sleepaway Camp? What would otherwise be a shameless Friday the 13th knockoff remains iconic today thanks to its mind-melting final killer reveal.
The big twist announces that the shy, unassuming Angela (Felissa Rose) is not only the killer but also actually a boy, standing up to reveal a male anatomy, genitals and all, to survivors Susie (Susan Glaze) and Ronnie (Paul DeAngelo).
Though an opening prologue suggests that Angela's brother Peter was killed in a speedboat accident when they were children, the twist reveals that Angela was actually the one who died, and the kids' deranged Aunt Martha (Desiree Gould) forced Peter to dress as a girl and assume Angela's identity.
While the twist leads to a rather troubling bout of trans representation by contemporary standards, as a piece of storytelling it has shocked audiences for decades if only for how wildly unexpected it was.
Plus, who will ever forget Angela/Peter holding their mouth wide open and growling like a bear in the film's final shot? Haunting.
