When I discovered there was a film called Diary of an Erotic Murderess starring the ludicrously gorgeous Marisa Mell I was obviously going to be interested. Having seen it, it would only be fair to say that it does not live up to the promise of its title plus its star. But hey ho, it still has its moments and is a decent enough Spanish psychological thriller. In it, Gina - played by Marisa Mell - is a con artist who is hired by a millionaire to work as a nanny looking after his deranged son. She soon realises that her considerable charms are a route to the old man's money, so she concocts a plan to get her hands on it. This involves the finding of a secret diary written by the millionaire's late wife; a journal that tells tales of her husband's abuse and her plans to murder him. But like most films of this type, events do not go entirely to plan.
Well, despite the title, this one isn't really too erotic unfortunately. Its chief selling point is Marisa Mell though. She was something of a cult actress who starred in a number of interesting Euro flicks, most notably Mario Bava's Danger: Diabolik. This one, along with the superior The Great Swindle, is a Spanish thriller where she was given the lead role. But even though she is a compelling presence, this movie never amounts to as much as its potential suggests it might. It's a fairly standard unremarkable psychological thriller overall, although it does have some bizarre aspects that admittedly don't really go anywhere. For instance Gina is researching the subject of Galician witches and in doing so discovers that the Holy Grail is present somewhere in the mansion she now lives. This incredible plot development is covered in a bizarrely understated manner but it doesn't really lead to anything much ultimately. Overall the mood is quite laid-back, partially because of Carlo Savina's lush score. But despite all this it does end on a commendably disturbing note. This one is probably best left to fans of Ms Mell; otherwise it's not overly memorable.
