Superbad is a 2007 American coming-of-age teen buddy comedy film directed by Greg Mottola, written by Seth Rogen and Evan Goldberg, and produced by Judd Apatow. It stars Jonah Hill and Michael Cera as Seth and Evan, two teenagers about to graduate from high school. Before graduating, the boys want to party and lose their virginity, but their plan proves harder than expected. Christopher Mintz-Plasse (in his film debut), Rogen, Bill Hader, Martha MacIsaac, and Emma Stone (in her film debut) provide supporting roles.

Rogen and Goldberg wrote the script during their teenage years. It is loosely based on their experience in Grade 12 at Point Grey Secondary School in Vancouver during the 1990s. The main characters have the same given names as the two writers. Rogen was also initially intended to play Seth, but due to age and physical size this was changed, and Hill went on to portray Seth, while Rogen portrayed the irresponsible Officer Michaels, opposite Saturday Night Live star Hader as Officer Slater.

Superbad premiered at Grauman's Chinese Theatre on August 13, 2007, and was theatrically released in the United States four days later on August 17, 2007. The film received positive reviews, with critics praising the dialogue and the chemistry between the two leads as well as the performances of the supporting cast. The film also proved financially successful, grossing $170.8 million on a $17.5–20 million budget. The film has since become a cult classic, considered among the best comedy films of all time.

Seth and Evan are unpopular high school seniors who have been best friends since childhood, and hope to lose their virginities before going to different colleges. Jules, a girl Seth is attracted to, invites him to a party at her house. Seth and Evan's friend Fogell has a fake ID, so Seth promises to buy Jules alcohol. Evan runs into Becca, with whom he is infatuated, and offers to get her alcohol as well.

Fogell attempts to buy the alcohol at a liquor store with his fake ID under the mononym "McLovin". His attempt seems to work as the clerk accepts his fake ID and starts to ring up the transaction, but mid-transaction, Fogell is knocked down by a robber before he can purchase the alcohol. When police officers Slater and Michaels arrive, Seth and Evan, who are outside, believe that Fogell is being arrested. While waiting outside the liquor store, Seth is hit by a motorist. In exchange for their not reporting him, the motorist promises to take them to another party where they can get alcohol. Meanwhile, after getting his statement, the officers agree to drive Fogell to the party. Despite being on duty, they start drinking. Bonding with Fogell, they engage in various shenanigans.

At the party, Seth plans to steal alcohol while Evan is hesitant to stay. The motorist is kicked out by the party host and a fight ensues; Evan decides to leave despite Seth's insistence he stay. Seth then dances with a drunk Jacinda, who stains his leg with menstrual blood. Seth is confronted by the party's host for dancing with his fiancée, and a brawl ensues. The police are called, and Seth and Evan reunite outside and escape. Seth chastises Evan for bailing on him, reminding him that they had lifelong plans to attend college together. Evan retorts that Seth is selfish and holds him back. Evan shoves Seth, who is struck by the police cruiser driven by a distracted Slater. The officers plan to blame the crash on Seth and Evan, but as Fogell emerges from the car, all three flee. Reunited, the trio make their way to Jules' party.

At the party, Fogell inadvertently reveals that he and Evan will be living together at college, upsetting Seth. He then delivers the alcohol to Jules and begins drinking heavily. Meanwhile, Becca attempts to seduce Evan to take her virginity, but he declines as she is drunk and may regret it. Meanwhile, Fogell impresses classmate Nicola, so she takes him upstairs to have sex. Seth drunkenly attempts to kiss Jules, but she declines because she does not want to kiss him while he is drunk. Believing he has ruined his chance, Seth becomes upset and falls down in a drunken stupor, accidentally headbutting Jules and giving her a black eye.

Slater and Michaels bust the party. Seth wakes up and escapes, carrying an intoxicated Evan away from the house. Slater busts in on Fogell and Nicola, causing her to run off. Slater and Michaels reveal they knew all along that Fogell was underage but played along, wanting to show him that cops can have fun too. To make it up to him, they make a fake spectacle of perp-walking him to their cruiser in front of his classmates. They then destroy the damaged police cruiser together.
