Graffiti's cast of teens — including Richard Dreyfuss and Ron Howard — has serious decisions to make on a late-summer night filled with rock music and hot rods, the kind that can only be made if they stay up 'til dawn. Should they ditch town for college? Should they stay with their gals? Whatever the choice, it infuses this most innocently joyous eve-of-adulthood film with that bittersweet feeling of leaving one's childhood behind.
