Friday the 13th is a 1980 American independent horror film directed by Sean S. Cunningham and written by Victor Miller. The film stars Betsy Palmer, Adrienne King, Harry Crosby and Kevin Bacon in one of his earliest roles. The film concerns a group of teenagers who re-open an abandoned camp site years after a young boy drowned in a lake located nearby. One by one, the teens fall victim to a mysterious killer.
Friday the 13th, inspired by the success of John Carpenter's Halloween, was made on an estimated budget of $550,000. Although it was poorly received by film critics, it grossed over $39.7 million at the box office in the United States, and went on to become one of the most profitable slasher films in cinema history; it was also the first movie of its kind to secure distribution in the USA by a major studio, Paramount Pictures. The film's box office success led to a long series of sequels, a crossover with Freddy Krueger and a remake currently in development.
The film then moves forward to Friday, June 13, in the present day; a young woman named Annie (Robbi Morgan) enters a small diner and asks for directions to Camp Crystal Lake, much to the shock of the restaurant's patrons and staff. A strange old man named Ralph (Walt Gorney) reacts to the news of the camp's reopening by warning Annie that they are "all doomed". Enos (Rex Everhart), a truck driver from the diner, agrees to give Annie a lift halfway to the camp. During the drive, he warns her about the camp, informing her that a young boy drowned in Crystal Lake in 1957, one year before the double murders occurred. After Enos lets her out, Annie hitches another ride in a Jeep. The second driver, whose face is never seen, murders Annie by slashing her throat with a large hunting knife.
At the camp, the other counselors, Ned (Mark Nelson), Jack (Kevin Bacon), Bill (Harry Crosby), Marcie (Jeannine Taylor), Brenda (Laurie Bartram), Alice (Adrienne King) and the camp's owner, Steve Christy (Peter Brouwer), are refurbishing the cabins and facilities. As a violent storm closes in on the horizon, Steve leaves the campgrounds to get more supplies. The unidentified killer begins to isolate and murder the counselors. Later that evening, Steve returns from town and is also murdered, apparently familiar with his attacker. Alice informs Bill that she saw the lights turn on at the archery range and that she thinks she heard Brenda screaming. Bill and Alice leave the cabin to investigate, and find a bloody axe in Brenda's bed. Attempting to phone the police, they discover the phones are dead and that the cars won't start when they try to leave. When the lights go out all over the camp, Bill goes to check on the power generator. Alice heads out looking for Bill when he doesn't return; she finds his body pinned to a door by several arrows. Now alone, Alice flees back to the main cabin and hides. After a few moments of silence, Brenda's corpse is hurled through the window.
Alice hears a vehicle outside the cabin and, thinking it to be Steve, runs out to warn him. Instead, she finds a middle-aged woman who introduces herself as Mrs. Voorhees (Betsy Palmer), stating that she is an "old friend of the Christys'". Alice hysterically tries to tell her about the murders. Mrs. Voorhees expresses horror at the sight of Brenda's body, but she soon reveals herself to be the mother of the boy who drowned in the lake in 1957, and that today is his birthday. Talking mostly to herself, she blames her son Jason's drowning on the fact that two counselors were having sex and were unaware of Jason struggling in the lake. Mrs. Voorhees suddenly turns violent and pulls out a knife, rushing at Alice. A lengthy chase ensues, during which Alice flees her attacker and finds Steve and Annie's bodies in the process. Alice and Mrs. Voorhees have multiple confrontations, each time with Alice believing she has finally beaten Mrs. Voorhees. During their final fight, Alice manages to decapitate Mrs. Voorhees with her own machete.
Afterwards, Alice boards a canoe and floats to the middle of the lake. As the sun rises, the decomposing "corpse" of Pamela's son, Jason (Ari Lehman), attacks Alice while she waits for help in a canoe. Just as she is dragged under water Alice awakens in a hospital, where a police officer tells her that they pulled her out of the lake. Alice is informed that everyone is dead; when she asks about Jason, the officer informs her they never found any boy, which leaves her with the impression that he is still at the lake.
Friday the 13th was produced and directed by Sean S. Cunningham, who had previously worked with filmmaker Wes Craven on the film The Last House on the Left. Cunningham, inspired by John Carpenter's Halloween, and films by Mario Bava, wanted Friday the 13th to be shocking, visually stunning, and "[make] you jump out of your seat." Wanting to distance himself from The Last House on the Left, Cunningham wanted Friday the 13th to be more of a "roller-coaster ride".
This film was intended to be "a real scary movie" and at the same time make the audience laugh. Friday the 13th began its life as nothing more than a title. Initially, "Long Night at Camp Blood" was the working title during the writing process, but Cunningham believed in his "Friday the 13th" moniker, and quickly rushed out to place an ad in Variety. Worried that someone else owned the rights to the title and wanting to avoid potential lawsuits, Cunningham thought it would be best to find out immediately. He commissioned a New York advertising agency to develop his concept of the Friday the 13th logo, which consisted of big block letters bursting through a pane of glass. In the end, Cunningham believed there were "no problems" with the title, but distributor George Mansour stated, "There was a movie before ours called Friday the 13th: The Orphan. Moderately successful. But someone still threatened to sue. I don't know whether Phil [Scuderi] paid them off, but it was finally resolved.
The film was shot in and around the township of Blairstown, New Jersey in the fall of 1979. The camp scenes were shot on a working Boy Scout camp, Camp No-Be-Bo-Sco.
Since Mrs. Voorhees, the killer in the original Friday the 13th, does not show up until the final reel of the film, Manfredini had the job of creating a score that would represent the killer in her absence. Manfredini was inspired by the 1975 film Jaws, where the shark is not seen for the majority of the film but the motif created by John Williams cued the audience on when the shark was present during scenes when you could not see it. Sean S. Cunningham sought a chorus, but the budget would not allow it. While listening to a Krzysztof Penderecki piece of music, which contained a chorus with "striking pronunciations", Manfredini was inspired to recreate a similar sound. He came up with the sound "ki ki ki, ma ma ma" from the final reel when Mrs. Voorhees arrives and is reciting "Kill her mommy!" The "ki" comes from "kill", and the "ma" from "mommy". To achieve the unique sound he wanted for the film, Manfredini spoke the two words "harshly, distinctly and rhythmically into a microphone" and ran them into an echo reverberation machine. Manfredini finished the original score after a couple of weeks, and then recorded the score in a friend's basement. Victor Miller and assistant editor Jay Keuper have commented on how memorable the music is, with Keuper describing it as "iconographic". Manfredini says, "Everybody thinks it's cha, cha, cha. I'm like, 'Cha, cha, cha? What are you talking about?"
The film came in at #31 on Bravo's 100 Scariest Movie Moments for the ending sequence, and was voted #15 in Channel 4's 100 Greatest Scariest Moments.
A remake of Friday the 13th is in development, with Freddy vs. Jason writers, Damian Shannon and Mark Swift, currently hired to script the new film. The film is reported to focus on Jason Voorhees, and that he will keep his trademark hockey-mask. The film is being produced by Michael Bay, Andrew Form, and Brad Fuller through Bay's production company Platinum Dunes, for New Line Cinema. In November 2007, Marcus Nispel, director of the 2003 remake of The Texas Chainsaw Massacre, was hired to direct.
