The chirpy, Euro-Barbara Windsor squeaking soundtrack that introduces this film would perhaps fool you into think you're about to watch some "Whoopsy-Boing!" sex comedy, but you'd be wrong. Except for the sex bit.

A horrible rich lady who has an open marriage with her Roman noble husband (Silvano Tranquili) is found dead within a locked room, her throat cut. Everyone thinks it was suicide...well, the police think it was suicide, but no one else does, especially housekeeper Magda, who now tends to the needs of Silvano and his mistress, photographer and professional moody looking smoker Rosalba Neri.

A spanner is thrown into the works when the rich lady's daughter from a previous marriage turns up after quitting boarding school (or something like that). Her wide eyed innocence certainly catches the eyes of Rosalba, who quickly bonds with the girl by taking loads of pictures of her and conveying the idea that she may bat for both sides, as it were. Silvano's eyebrows are certainly raised when comes home to find his step-daughter bare-arsed in front of a mirror, but if this newcomer has a legit stake in the money left by the rich jerk lady, what are out scheming twosome going to do about it?

This is more of your old-school giallo set in a big house with rich people being duplicitous and trying to out-do each other, with the usual plot twists thrown in for good measure, and a whole heap of photographer sessions between the young girl and a drooling Rosalba Neri. Obviously the girl gets it on with both the lead actors but you don't get a slow motion lesbian sex scene like you did with Silvio Amadio's previous Amuck. That said, those looking for nudity won't be let down as the stepdaughter seemingly spends half the film naked.

I've got to admit that I found the soundtrack really irritating. "A-chi-chi-chi-di-di-dididida-chi...aaaaaaaah!" indeed.

The sinfully slinky 'Smile Before Death' aka 'Il Sorriso della iena' (1972) remains a bizarrely under scrutinized, salaciously saucy slasher from cult Italian film-maker, Silvio 'Amuck!' Amadio. This deliciously deviant, unjustly obscure, sublimely sexy, full-bloodied, sensuously soft-bodied Giallo features that deliciously divine brunette Rosalba Neri, the wickedly sultry queen of B-Movie scream and hellaciously hunky, Hiram Keller as a voluptuously-villainous duo plotting to do most grievous harm to the stepdaughter of Hiram's resolutely ill-minded character.

Bravura genre director Silvio Amadio's breezily stylish and frequently raunchy follow-up to "Amuck!" is fulsomely engorged with giddy plot twists, plentifully lurid stalk an' slash, and is busily replete with the ubiquitous "shock" ending rabid Gialli/thriller fans so ardently crave! 'Smile before Death' is most certainly guaranteed to amuse and bemuse in equally confounding measure, and remains an entirely worthy entry to this most histrionic of iconoclastic, bombastic film idioms. This gorgeous Giallo's relative rarity is wholly undeserved and one sincerely hopes that eventually it will soon get a glisteringly-restored Italian language, UK-friendly, feature-loaded DVD/Blu-ray release that this tremendously exciting thriller so earnestly deserves!

From the director of the better known "Alla Ricerca del Piacere" (aka "Amuck!") comes this stylish thriller that involves not only a confusing web of love affairs and relationships, but also - towards the climax - a bundle of twists that are guaranteed to surprise every viewer without becoming implausible at any moment.

And this is the big plus of this movie: The twists all work. The first half moves on relatively slow (similar to Silvio Amadio's above mentioned earlier Giallo),but the viewer already gets enough information to know that the plot isn't as simple as it seems. In the second half the film becomes a roller coaster ride of red herrings, plot twists and other surprises, which makes it decisively superior to Amadio's earlier effort.

The acting is also thoroughly convincing, which is especially important once the film is finished and the viewer gets the whole story. But the most remarkable thing in this intriguing Giallo is the lush, ear-catching main theme that will never let one go after being heard for the first time.
