Hold On to the VHS version of Lisa and the Devil
First of all, ignore the butchered version, HOUSE OF EXORCISM, which is actually a heavily edited version of LISA AND THE DEVIL to redo the movie of Lisa as a possessed victim.
Buy the VHS or DVD version of LISA AND THE DEVIL.
Now why is the VHS version valuable? The VHS version has the deleted scenes of Lisa's chloroformed rape and Sylvia Koscina's highly explicit sexual intercourse scene. It was almost X-rated. It showed everything which startled me since I did not expect to see such explicit nudity and graphic sex. Lisa's chloroformed rape scene, by contrast, is tame and is limited to showing her garments being removed and she's topless then Max kisses her. For some reason, the DVD version omits these deleted scenes.
