The Complete List of Cult Movies (Wikipedia) - Page 15

A cult film, also commonly referred to as a cult classic, is a film with a cult following, obscure or unpopular with mainstream audiences, and often revolutionary or ironically enjoyed. Sometimes, the definition is expanded to exclude films that have been released by major studios or have big budgets, try specifically to become cult films, or become accepted by mainstream audiences and critics. Cult films are defined as much by audience reaction as they are content.
