American Pie is a 1999 American sex comedy film directed and co-produced by Paul Weitz (in his directorial debut) and written by Adam Herz. It is the first film in the American Pie theatrical series and stars an ensemble cast that includes Jason Biggs, Chris Klein, Alyson Hannigan, Natasha Lyonne, Thomas Ian Nicholas, Tara Reid, Mena Suvari, Eddie Kaye Thomas, Seann William Scott and Eugene Levy. The plot centers on five best friends (Jim, Kevin, Oz, Finch, and Stifler) who attend East Great Falls High. With the exception of Stifler (who has already lost his virginity), the youths make a pact to lose their virginity before their high school graduation.
The title is borrowed from the song of the same name and refers to a scene in which the protagonist is caught masturbating with a pie after being told that third base feels like "warm apple pie". Writer Adam Herz has stated that the title also refers to the quest of losing one's virginity in high school, which is as "American as apple pie."
The film was a box-office hit and spawned three direct sequels: American Pie 2, American Wedding, and American Reunion. In addition to the primary American Pie saga, there are five direct-to-DVD spin-off films bearing the title American Pie Presents: Band Camp, The Naked Mile, Beta House, The Book of Love and Girls' Rules.
In response to the success of American Reunion, a fifth theatrical film, under the working title American Pie 5 was announced on August 4, 2012. In August 2017, Seann William Scott said in an interview that the fourth film probably had not made enough at the domestic box office to warrant another film.
