The 1973 coming-of-age classic "American Graffiti" turns 40 this week. George Lucas's semi-autobiographical tale of teenage-hood in post-World War II California is as nostalgic as movies come, especially when you take a look back at some of the now famous careers it launched.

Aside from Lucas himself, fresh-faced Ron Howard and Harrison Ford are the movie's most famous and successful alumni. But what about the rest of the film's memorable cast? Some stars have fallen off the radar, some have had public struggles with their inner demons, and others are sadly no longer with us.

Take a look below to find out where the cast of "American Graffiti" is now.
