Chilling, well-observed thriller, whose message seems to be: "Careful when you're making telephone pranks, you never know whom you might mess with!". The bland cinematography gives it a TV-movie look, but it still has natural , believable performances by Ladd and Keanan, a well-cast actor as the handsome psycho, a good ear for dialogue and some moments that would make Hitchcock proud (especially the scene where the girl is trapped in the back seat of the killer's car).
