Lisa and the Devil was a film directed by Mario Bava, it had a limited cinema release in 1973 but was soon withdrawn by producer Alfredo Leone as he did not know how to market this strange, lyrical film. It sat on the shelf for a couple of years with no distributer interested in picking it up, so Leone decided to attempt to make some money back on his investment. Two years later he returned with one of the participants from the first film, Elke Sommer - along with Robert Alda and Carmen Silva, neither of whom appeared in Lisa and the Devil at all - and, with Bava's assistance, directed a batch of new, completely unrelated material. He then merged these new scenes in with parts from the original film. The resultant movie became known as The House of Exorcism. Like some other Italian films from the time like L'anticristo it clearly was designed to cash in on the success of The Exorcist, as it is basically a rip off of this film in many ways. Lisa and the Devil, on the other hand, had nothing to do with demonic possession and its story is completely unrelated.
The biggest single problem with The House of Exorcism is that if you are already familiar with Lisa and the Devil it's very difficult disassociating the scenes from that movie from their original intent. It simply just makes you want to see them again in their original context. When I watch The House of Exorcism, it's the new bits that interest me; the stuff from Lisa is just simply distracting. The contrast in tone between the two sections of film is massive, where the stuff from Lisa is beautiful and fairly subtle; House of Exorcism is relentlessly coarse and goes for shock value. It's pretty much an exploitation movie and the sequences from Lisa and the Devil do not fit into its tone and story-line well at all. In fairness, it may work a lot better - maybe even quite well - if you have never seen the original film but I suspect most people going into this already have and that's essentially the problem.
The new material is set mainly in a hospital where Lisa (Elke Sommer) is confined after being possessed by the Devil. A priest (Robert Alda) tries to exorcise her. The new scenes are typified by Sommer barking out obscenities at Alda. There's lots of green vomit, a vision of a beautiful naked woman and...frogs. The new stuff's not that bad really and would have no doubt have made an entertaining schlockfest if it had constituted the full movie. But, as it is, the majority of the run-time is made up of re-used material from Lisa and the Devil, which is distracting and useless if you have seen the original already. Nowadays, with the original film readily available, The House of Exorcism has become no more than a curiosity piece. Fun to watch for the added possession material but as a whole it doesn't work anymore.
