Murder Obsession is an odd confection of a movie. It includes various famous Italian exploitation favourites (John Richardson, Laura Gemser, etc.) in a tale of a young actor's return to his family mansion to film location shots and inflict his movie friends upon his ever-so-slightly bonkers mother. Convinced by his mum that he was responsible for his famous conductor dad's death, various skeletons tumble out of closets as well as real bodies (with some gory but very dodgy effects by Sergio Stivaletti). The film veers into true delirium towards the climax (almost invoking the spirit of Argento's 'Suspiria') but apart from the killings, the film's pace is painfully slow. A too so-so epitaph to an Italian horror great.
