3) “The Human Centipede 2” (2011)
The Human Centipede 2 (Full Sequence) is a 2011 Dutch black and white exploitation film written, directed, and co-produced by Dutch filmmaker Tom Six.
The first “The Human Centipede” was a young woman found herself sewn mouth-to-anus by a sadistic surgeon with two other victims. Every cloud has a silver lining. In “The Human Centipede 2 (Full Sequence)” we meet the same actress (Ashlynn Yennie), and from what we can judge she survived that ordeal with little permanent facial damage.
It was originally banned in many countries.
4) “Antichrist” (2009)
Antichrist is a 2009 Danish experimental horror film written and directed by Lars von Trier.
It tells the story of a couple who, after the death of their child, retreat to a cabin in the woods where the man experiences strange visions and the woman manifests increasingly violent sexual behavior and sadomasochism. The narrative is divided into a prolog, four chapters, and an epilog.
