"Cruising" (1980) This is considered by many to be a classic in the Gay Film genre....partially due to the controversy surrounding the film itself (as well as the reported deleted scenes) and partly due to the ground-breaking nature of the subject material. For a 1980's mainstream release -- it IS pretty racy in context.
Al Pacino portrays an undercover cop in the NYPD. His assignment requires him to infiltrate the world of the underground S&M/Leather subculture of the gay community. His goal is to identify a serial killer who has been seducing and brutally murdering several gay men over the past few months. From what I gather, this film is based on a novel...which was based on a real-life series of homicides in 1970's NYC.
It is a pretty decent film (as far as early 80's films go) and worth having in the "Have Seen" column of LGBT films.....but I'm not really sure the film answers all of the questions it seems to ask. [3/5]
