Fast Times at Ridgemont High is a 1982 American coming-of-age comedy film written by Cameron Crowe, adapted from his 1981 book of the same name. Crowe went undercover at Clairemont High School in San Diego and wrote about his experiences.
The film was the directorial debut of Amy Heckerling and chronicles a school year in the lives of sophomores Stacy Hamilton (Jennifer Jason Leigh) and Mark Ratner (Brian Backer), and their respective older friends Linda Barrett (Phoebe Cates) and Mike Damone (Robert Romanus), both of whom believe themselves wiser in the ways of romance than their younger counterparts. The ensemble cast of characters form two subplots with Jeff Spicoli (Sean Penn), a perpetually stoned surfer, facing off against uptight history teacher Mr. Hand (Ray Walston), and Stacy's older brother, Brad (Judge Reinhold), a senior who works at a series of entry-level jobs in order to pay off his car, and who is pondering ending his two year relationship with his girlfriend, Lisa (Amanda Wyss).
In addition to Penn, Reinhold, Cates and Leigh, the film marks early appearances by several actors who later became stars, including Nicolas Cage, Forest Whitaker, Eric Stoltz, and Anthony Edwards. Among these actors, Penn, Cage, and Whitaker would later win the Academy Award for Best Actor, with Penn winning twice.
In 2005, the film was selected for preservation in the United States National Film Registry by the Library of Congress as being "culturally, historically, or aesthetically significant".
