The Beyond: Mario Bava’s A Bay of Blood



Italian genre cinema is known for its baroque titles—some films seem to boast more names than cast members. Post-war filmmakers were driven to market their movies to as wide an audience as possible, banking on popular trends. But the absurdly long collection of titles attached to Mario Bava’s 1971 film A Bay of Blood (aka Twitch of the Death Nerve) is more telling than it first appears. 

The film’s original title, Reazione a catena—which translates to “chain reaction” in Italian—describes the maestro’s pioneering film perfectly. Bava dispatches with his characters in gruesome ways. His plot about a familial inheritance drama exists only to propel us to the next kill. Bay of Blood is often categorized as a giallo film, and it bears a few hallmarks of the genre (red herrings and a glimpsed black-gloved killer), but what Bava has created here is an early prototype for the slasher film—one that predates Bob Clark’s Black Christmas (the 1974 movie is widely regarded as the first in the genre). In this way, Reazione a catena takes on a dual meaning, with Bava’s movie setting off a chain reaction in horror cinema one decade later—a host of violent works that fixated on body-count over everything else.

In case you needed further proof of A Bay of Blood’s influence, look to the film’s bucolic setting (and ominous body of water), a death scene where one character is slaughtered with a machete-like instrument to the face, and the double impalement of two young people having sex—all found in the Friday the 13th series (Part 2 blatantly rips off the aforementioned scenes). Other imitators can be found in the film’s alternate titles, specifically The Last House on the Left, Part II, the American reissue. This was a cheap way for distributors to cash in on the controversy generated by Last House on the Left, Wes Craven’s film released a year after Bava’s. Any ties to Craven’s postmodern contribution to the slasher genre with the Scream series are amusing, but incidental.

Bava himself had an absurdist sense of humor with a nihilistic streak, which he injects into A Bay of Blood’s theme of man versus nature. “Man should live and let live, and without any interfering,” one character opines to another who studies insects in captivity. “If you kill for killing’s sake, you become a monster.” And that’s exactly what happens as the film’s cast of unlikable characters murders each other in grisly ways. “But man isn’t an insect. We have centuries of civilization behind us,” the insect collector retorts. Bava reveals these greedy players are no better than the beetles that squirm in the mud and float in the bay. In the film’s opening, the elderly countess who owns the highly sought-after plot of land is strangled to death, but her murderer is abruptly slayed before he can enjoy the fruits of his bloody labor.

The joke is on us, too. Bava highlights his darkly comedic perspective by contrasting sunny location shots with scenes of brutality, set to Stelvio Cipriani’s strangely upbeat score. The woodland setting is a work of camera trickery since Bay of Blood’s shooting location lacked the desired forestry. The film’s surprise ending is perhaps the biggest gag of all.

Bava’s reputation as a master visual stylist precedes him (Black Sunday, Blood and Black Lace), but in Bay of Blood, the maestro toys with his characters while pulling his audience’s strings, too. According to legend, Christopher Lee, the star of Bava’s 1963 film, The Whip and the Body, walked out of a screening of Bay of Blood in disgust. One can imagine the grin on Bava’s face at the fact. A Bay of Blood is a historically significant film and a cautionary tale about the perils of human nature, but it’s also a gore-soaked lark from one of the horror genre’s most vital filmmakers.
