O.C. and Stiggs is a 1987 film directed by Robert Altman, based on two characters that were originally featured in a series of stories published in National Lampoon magazine. The film stars Daniel H. Jenkins and Neill Barry as the title characters. Other members of the cast include Paul Dooley, Jane Curtin, Martin Mull, Dennis Hopper, Ray Walston, Louis Nye, Melvin Van Peebles, Tina Louise, Cynthia Nixon, Jon Cryer and Bob Uecker.
King Sunny Adé appears in the film and provided the score.
The film, a raunchy teen comedy described by the British Film Institute as "probably Altman's least successful film," was not released after post-production was completed. MGM shelved it for a couple of years, finally giving it a limited theatrical release in 1987 and 1988. In an interview years later, included on the DVD release of Tanner '88, Altman acknowledges that the film didn't work but is quick to defend the cast, which included Tanner star Cynthia Nixon, saying it was "not their fault."
