Blood Delirium (1988)

After his beloved wife dies, an unbalanced painter who believes himself to be the reincarnation of Vincent Van Gogh goes over the edge and digs up her corpse--with the help of his necrophiliac butler--to bring it back to his castle and use it for "inspiration". He soon meets a beautiful musician who looks exactly like his late wife and brings her back to his castle. However, she eventually discovers their secret: the butler murders young women, disposes of their bodies and uses their blood--"the color of life"--for the artist's paints.
