Universal Pictures
It was shot in Northern California on a tight budget over the course of 29 days -- nobody expected "American Graffiti" to become a hit when it was first released in the summer of 1973. But audiences connected with the film's nostalgic tale of a group of high school graduates cruising around listening to rock-n-roll favorites. Directed and co-written by George Lucas, "American Graffiti" features vignettes documenting the night of a group of teenagers in the 1960s.
The sequel, "More American Graffiti," reunited much of the cast and crew (with the exceptions of Richard Dreyfuss and Lucas), but that film was considered somewhat of a dud in comparison with the original.

Ron Howard as Steve
Universal Pictures
Howard was perhaps the most well-known cast member of "American Graffiti" at the time of the film's release. He was just 6 years old when he began appearing on "The Andy Griffith Show" as Sheriff Taylor's son Opie, a role which he went on to play for eight seasons. At 18, Howard was looking to break away from his Mayberry image when he was cast as Steve Bolander, a high school graduate who feels pressure from his local girlfriend not to leave their small town behind to attend college in the East.

One year after the release of "American Graffiti," Howard found more success as Richie Cunningham on TV's "Happy Days," another nostalgic project set during the time of hot-rods and drive-ins. Following "Happy Days," Howard went on to become a prominent Oscar-winning director, with hits like "Splash," Cocoon," "Backdraft," "Apollo 13," "A Beautiful Mind" and "The Da Vinci Code." Howard also serves as the executive producer and narrator of the cult series, "Arrested Development." Married to wife Cheryl since 1974, Howard has four children, two of whom (Bryce Dallas and Paige) have also become actors.
Richard Dreyfuss as Curt
Universal Pictures
Dreyfuss beat out about 100 other unknown actors at the time for the role of main character Curt, who, like Howard's character, also had trouble deciding whether or not he really wanted to leave his small-town life behind for a fresh start at college.

"American Graffiti" gave Dreyfuss great exposure. He used that success to launch a high-profiled film career, with starring roles in two of Steven Spielberg's biggest hits, "Jaws" and "Close Encounters of the Third Kind." In 1978, Dreyfuss scored a best actor Oscar for "The Goodbye Girl" before achieving more accolades in 1980s and 1990s with his performances in films like "Down and Out in Beverly Hills" and "Mr. Holland's Opus." Dreyfuss turns 66 in October and he still continues to work steadily. According to IMDb, Dreyfuss has four upcoming film releases either completed or in post-production.

Ford teamed up with George Lucas, the director of "American Graffiti," once again for the original "Star Wars" trilogy before going on to hits "Blade Runner," "Witness," "Working Girl," "The Fugitive," "Air Force One" and "The Indiana Jones" films among others. In the years that have followed "American Graffiti," the iconic roles of Hans Solo and Indiana Jones have helped Ford become a cinematic legend. Even today, the 71-year-old actor still stands at the top of Hollywood's A-list. Upcoming roles include a part in "Anchorman: The Legend Continues," as well a planned fifth "Indiana Jones" installment. There's also been talk of Ford possibly reprising his Solo role for Disney's upcoming "Star Wars" sequel. As if he doesn't have enough going on, Ford is set to star in "The Expendables 3."
