LONDON (AP) — British filmmaker Stanley Long, whose cheap-and-cheerful soft-core romps saw him dubbed the "king of sexploitation," has died at the age of 78.

Long's family says he died Monday of natural causes in Buckinghamshire, southern England. The exact cause of death was not specified.

A producer, director and cinematographer, Long created movies with titles like "Nudist Memories" and "The Wife Swappers" before scoring his biggest success with "Adventures of a Taxi Driver" and other 1970s' sex comedies.

The mix of bawdy humor and nudity in "Adventures" was a hit. The film was sold to 36 countries and spawned two sequels.

Long also set up the post-production company Salon, which has worked on big-budget movies including "V for Vendetta" and "Batman Begins."
