In The Realm of the Senses (1976) – Japan
Gut-wrenching, visceral, and sexually explicit, this movie is one of the best erotic films ever made. Directed by Nagisa Ōshima, In The Realm of the Senses is based on the true story of Sada Abe, who murdered her lover in erotic asphyxiation in 1936. But that's not the shocking part. After her partner's death, Sada then cut off his penis and carried it around with her for days before the police found her. So, you may think you know the ending, but that's just the plot. The film is an insightful experience into an erotic work of art, with the ability to sexually arouse the viewer, but at the same time reduce the stimulation to revolt, shock, and awe. However vile and unsettling, if you finish the movie until the end with a profound understanding, you'll realise that it is a movie about love. Plus, the fact that it’s a true story, makes it a very sad one. You definitely won't forget this one.
