I love any movie that opens with its own personalized rap song. This was commonplace during the 1980s and early 90s as soundtrack sales proved to be just as lucrative as the movies themselves.
Made in 1986 in the British Isles, "Rawhead Rex" is based on a short story penned by Clive Barker in his Books of Blood series, and it's always gotten pretty shafted with distributions. Now most people know it vaguely as “the film where the monster pees on the priest.”
Set in the neon grime of 1980’s New York City, Liquid Sky focuses on the new wave/punk performance art movement complete with copious amounts of sex and drug use.
