"Death in Haiti" is by no means a stellar or exceptional Giallo, but it's nevertheless a modest pioneer of some sort. Its release year was 1972, and that year is widely considered as the peak-performance for the Italian Giallo. In other words, up until 1972, and still even 2-3 years after, all Giallo writers and directors largely followed the proven success formula. It wasn't until after the mid-70s, when the popularly of these films started to decrease, that they began experimenting with filming locations outside of Italy or mixing typical Giallo plots with elements from other exploitation sub genres. Directors Giampaolo Lomi and Edoardo Mulgargia were among the first ones to take the authentically Italian concept abroad, evidently to Haiti in this case, and added the aspects of psychedelic drugs and traditional voodoo rituals. Who knows, maybe they just wanted to treat themselves to a tropic holiday destination, but at least they also grabbed the opportunity to make an enjoyable Giallo at the same time!
Co-writer Anthony Steffen, formerly a Spaghetti Western star, invented a nicely glamourous role for himself as the respected Doctor Williams; surgeon and businessman on the island of Haiti. He's always surrounded by rich, dubious and sleazy people because Williams also happens to have invented a powerful new drug. Grace, the beautiful blond wife of William's childhood buddy Fred can confirm the drug is quite efficient, because it causes her to hallucinate about dozens of naked black men and having sex with a voodoo priest! With drugs and money involved, it naturally doesn't take long before people are getting killed in various gruesome ways by an unseen assailant. The Haitian locations are beneficiary for the film, even though the obligatory tribal/voodoo dance rites are rather tedious and basically just form a cheap excuse to depict gratuitous nudity. Those gorgeous native Haitian girls obviously dance topless, or what else did you think? The genuine typical Giallo-whodunit plot is naturally the best thing about the film, and I must say there's a fair amount of mystery and suspense around the identity of the sadist killer. The extremely brutal murder taking place in an abattoir already makes "Death in Haiti" worth tracking down.
