The giallo may have been pioneered by the great Mario Bava and spectacularly refined by Dario Argento, but Umberto Lenzi was developing the techniques and stylings we now know and love from the mid-1960s. Before he became known for schlocky horror trash like Eaten Alive!, Nightmare City and Cannibal Ferox, Lenzi was toying with rich socialites and exploring pulpy, dime-store stories that often involved ridiculous, labyrinthine plots, psychedelic interiors, and beautiful, untrustworthy women. These are all ingredients of the giallo, and some of these early Lenzi efforts hint at a director with an eye for kitschy visuals, something that certainly doesn't come to mind when you watch a native tribesman scalp a poor traveller in the despicable Cannibal Ferox. These eye-catching visuals are certainly present in his 1969 film So Sweet... So Perverse, but there isn't much else to hold the attention in this plodding soap opera.

Handsome, jet-setting socialite Jean Reynaud (Jean-Louis Trintignant) enjoys a lavish lifestyle of cocktail parties and shooting ranges, but he has grown bored and frustrated with the lack of passion in his marriage to the beautiful Danielle (Erika Blanc). To counter this, Jean sleeps with anybody who happens to catch his eye, including his friend Helene (Helga Line),and his head is turned by the woman who has just moved upstairs, Nicole (Carroll Baker). When he hears screams coming from above, he rushes to Nicole's aid, learning that she is stuck in an abusive sexual relationship with her husband Klaus (Horst Frank). As they spend more time together, the couple inevitably fall in love, yet whenever they escape for a weekend, Klaus always manages to track them down. After a night of passion, Nicole reveals that she and Klaus have actually been paid a hefty sum to lure in and eventually kill Jean, but that the one doing the hiring has not yet revealed themselves.

With such a cool-sounding title (yet another famous trait of the gialli),there is nothing sweet and little perverse about the film itself. Argento eventually set a high standard for story-telling and the slow-building of tension within a vital set-piece, and the likes of Lucio Fulci and Sergio Martino added gory violence and a graceful style into the mix, but So Sweet... So Perverse is frustratingly tame, failing to ignite much interest in the plot or generate any excitement when events take a more sinister tone. Where Lenzi ultimately excels is in the glossy cinematography and dazzling interiors, which are garish enough to amusingly satirise the world of these detached characters and their materialistic lifestyles. Images of sun-drenched locations, expensive suits and beautiful, provocative women add a sleazy glamour and seductive glaze to the film, a hedonistic way-of-life Lenzi is happy to indulge as he shrewdly condemns it. It isn't quite enough to prevent So Sweet... So Perverse from becoming little more than a curious cinematic artefact, that ultimately paved the way for better directors to come along and take this new genre by the scruff.

Carroll Baker's second of four films with Italian director Umberto Lenzi (whose standard predilection for amusingly arty camera angles, lesbian flirtations and bare-breasted women did little to enhance his reputation as a filmmaker) is agonizingly slow and woefully overlong. A French businessman, unfaithful to the haughty wife he no longer loves, becomes infatuated with the American woman living in the apartment above his, the apparent victim of spousal abuse. The men in Lenzi's giallo productions are never required to strip below the waist, leaving his actresses looking vulnerable and used. Baker manages to stay covered most of the time, but the role doesn't require anything additional from her. Poorly-dubbed, blurry-romantic escapades among the decadent and doomed. * from ****

Umberto Lenzi's early giallo - before the Argento influenced Seven Blood Stained Orchids - feel more like film noir than the standard films of the genre. Speaking of that same movie, it would also use the J. Vincent Edward song "Why." And while we're discussing influences, this movie is definitely feeling all sorts of Les Diaboliques.

Jean (Jean-Louis Trintignant, Amour) is a rich socialite who has come to the aid of Nicole (Carroll Baker!),a gorgeous woman mixed up with Klaus (Horst Frank, The Dead Are Alive). Sure, Jean is married, but that doesn't stop him from falling for her, even when he learns that she's been paid to kill him. Of course, his wife Danielle (Erika Blanc!) is mixed up in this, but Nicole is smarter than she seems. Beryl Cunningham (The Salamanders) is also in this as a dancer and Helga Line (Nightmare Castle) is on hand as well.

This was produced by Sergio Martino and has a screenplay by Ernesto Gastaldi, the writer of The Whip and the Body, The Possessed, The Sweet Body of Deborah and All the Colors of the Dark. And check out that Riz Ortolani score!
