BASEketball is a 1998 American sports comedy film by David Zucker starring South Park creators Trey Parker and Matt Stone, along with Dian Bachar, Robert Vaughn, Ernest Borgnine, Yasmine Bleeth, and Jenny McCarthy. The movie follows the history of the sport (created by Zucker years earlier) of the same name, from its invention by the lead characters as a game they could win against more athletic types, to its development as a nationwide league sport and a target of corporate sponsorship. This is the only work involving Parker and Stone that was neither written, directed, nor produced by them, although Zucker himself has said Parker and Stone contributed innumerable suggestions for the film, most of which were used.
