American Graffiti is a 1973 American coming-of-age comedy film directed and co-written by George Lucas starring Richard Dreyfuss, Ron Howard, Paul Le Mat, Harrison Ford, Charles Martin Smith, Cindy Williams, Candy Clark, Mackenzie Phillips, Bo Hopkins, and Wolfman Jack. Suzanne Somers and Joe Spano also appear in the film. Set in Modesto, California, in 1962, the film is a study of the cruising and rock 'n' roll cultures popular among the post–World War II baby boom generation. Through a series of vignettes, the film tells the story of a group of teenagers and their adventures over the course of a single night. In 1995, the United States Library of Congress deemed the film "culturally, historically, or aesthetically significant" and selected it for preservation in the National Film Registry.
