Horrors of Malformed Men

The setting is 1925. After breaking out of an asylum for the insane, a medical student finds that he's a dead-ringer for an heir to a fortune. Assuming the heir's identity, he soon makes his way to a sinister island ruled by a web-fingered mad scientist and his minions of malformed men and women. The last hour of this film is like nothing you have ever seen with many shocking moments of terror and torture. Incredible. This would undoubtedly be rated R for nudity and violence. Banned in it's home country of Japan for many years. In Japanese with English subtitles.
