Crash

A movie by David Cronenberg based on the novel by J.G. Ballard about a group of people who are sexually aroused by car crashes, a peculiar fetish arguably stemming from a pun on "auto-eroticism." They re-enact famous car crashes, cause accidents themselves and document other crashes. Both MPAA NC-17 and R versions have been produced.
