American Graffiti is a 1973 American coming-of-age comedy-drama film directed by George Lucas, produced by Francis Ford Coppola, written by Lucas, Gloria Katz, and Willard Huyck, and starring Richard Dreyfuss, Ron Howard, Paul Le Mat, Charles Martin Smith, Candy Clark, Mackenzie Phillips, Cindy Williams, and Wolfman Jack. Harrison Ford and Bo Hopkins also appear. Set in Modesto, California, in 1962, the film is a study of the cruising and early rock and roll cultures popular among Lucas' age group at that time. Through a series of vignettes, it tells the story of a group of teenagers and their adventures throughout a single summer night.
While Lucas was working on his first film, THX 1138, Coppola asked him to write a coming-of-age film. The genesis of American Graffiti took place in Modesto in the early 1960s, during Lucas's teenage years. He was unsuccessful in pitching the concept to financiers and distributors but found favor at Universal Pictures after every other major film studio turned him down. Filming began in San Rafael, California, but the production crew was denied permission to shoot beyond a second day. As a result, production was moved to Petaluma, California. It is the first film to be produced by his Lucasfilm production banner.
