Blood Delirium

Blood Delirium (1988) is a horror directed by Sergio Bergonzelli rated 4.5/10.

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.
