Body Double (1984) - Jumpscare Guide

Plot

Invited to stay at a posh house in Hollywood Hills, Jake Scully, a struggling actor, discovers the secret pleasure of voyeurism. When the nightly spying of his beautiful neighbor through the lens of a telescope isn’t enough to satisfy his desire, he begins stalking her. After inadvertently watching a gruesome murder, of which he is both the only witness and identified by the killer when he attempts to rescue the victim, the police blame Jake for watching the murder and trying to be a hero instead of calling authorities to the scene. Then, Jake meets Holly Body, and everything he thought he witnessed turns the murder case and the suspect list upside down.
