"Did you know that a young boy drowned? The year before those two others were killed?"
The first film in the Friday the 13th series, and the Trope Codifier for Slasher Movie genre. Released in 1980.Camp Crystal Lake has fallen on hard times. After several deaths in the late fifties and the sabotage of two other reopening attempts, the children's camp has remained an abandoned relic of the past. Steve Christy, the son of the camp's previous owners, plans another reopening and works hard to realize it. On the 13th of June, two weeks before the opening, the counselors Steve hired to run the camp arrive to help him.But someone else shows up as well — someone with murderous intent...
Friday the 13th contains examples of the following tropes:
Aborted Arc: It seemed that there was a relationship of some sort between Alice and Steve, but none of this is explained further.
Clueless Mystery: A lot of the film feels like we're supposed to be trying to figure out who the killer is...and then it's someone who was never mentioned before. Though funnily enough, these days it does feel like a twist that Jason isn't the killer.
Covers Always Lie: One version of the DVD cover for the first movie has a holographic image revealing Jason's mask. Not only does Jason not even show up in the first movie (except for a short dream sequence), he doesn't get the hockey mask for another two films.
Cut Phone Lines: As the killing intensifies, Camp Crystal Lake's phone lines are cut so that cast are stranded in the premises.
Leave the Camera Running: Through gratuitous Padding. Many times throughout the film a character exits the frame and we still haven't cut away. Whenever somebody drives away we see their vehicle ride all the way until exiting the frame (including Crazy Ralph on his bicycle). The worst shot is where Alice is making coffee, which lasts almost two minutes. The movie is at least 10 minutes too long. And only 90 minutes!
Rain of Blood: Marcie tells Jack that she has a recurring nightmare of a storm that turns into a rain of blood. This proves to be foreshadowing, as later blood starts dripping on Jack before he is killed.
Red Herring: Jason himself. This only occurs in hindsight, too: while characters mention a "young boy drowning" once, the film doesn't mention it again until Mrs. Voorhees comes in, and by the time she mentions Jason, her demeanor has outed her as the killer.
Shirtless Scene: Steve in his first scene. There's also the scene with the counselors swimming in the lake.
