TWITCH OF THE DEATH NERVE
A BAY OF BLOOD; BLOODBATH; CARNAGE; ECOLOGY OF A CRIME; THE LAST HOUSE ON THE LEFT PART II; THE NEW HOUSE ON THE LEFT
(Antefatto/Reazione a Catena)
Mario Bava sets up some stylish and imaginative set-pieces throughout. There is a captivating opening scene. An old lady in a wheelchair (Isa Miranda) moves through her house. Bava focuses on the lushness of the rich red drapery surrounding her while gentle piano music swells on the soundtrack, only for a noose to be thrown around her neck and the wheelchair kicked away and she left gasping as the wheels of the chair still spin. However, the sequence doesnt end there as the killer is then stabbed by another person. Elsewhere, there is a great scene where Brigitte Skay runs towards the lodge in a wet dress and the killer comes up behind and whacks her in the side of the neck with a machete. It is a scene that holds a considerable kick, none the more so for the full-frontal gore that Bava is prepared to throw at us, letting use see the machete buried all the way in the neck. Later there are shots of Roberto Bonanni getting a machete in the face; of Laura Betti having her head severed; Claudio Volonte having a spear thrown at them and being impaled to a tree. There is a particular imaginative sequence where two lovers are impaled in the midst of sex with a spear right through their bodies and the bed underneath them a set-piece that, to confirm Twitch of the Death Nerves influence on the slasher film, was later borrowed by Friday the 13th Part 2 (1981).
Being a former cinematographer, Bava makes a beautifully photographed film, filled with some exquisite shots of the bay and sunsets. On the minus side, much of the film is shot at night in seemingly natural lighting where it is difficult to see what is happening while watching the film on the small screen. Bava also characteristically over-indulges in the use of zooms, which is surely the cinematic equivalent of putting multiple exclamations points (!!!!!) in a sentence. Unlike a standard slasher movie, Bava takes a long time building up to the main action, spending too much time on the one-dimensional characters, especially the kids partying at the start. The dramas involving these people are dull as, very much akin the slasher movie, Twitch of the Death Nerve does little to establish them as being of any depth to care about.
There is not much plot to Twitch of the Death Nerve, it largely having been streamlined around the murder set-pieces. By the end, the film does gain a certain degree of black humour in the various twists where everybody keeps killing everybody else off. It reaches a bizarrely abrupt ending, where two kids shoot the remaining two survivors, by which time you can see that Mario Bavas tongue is now entirely planted in his cheek. Of course, by the end of the film, as Bava readily acknowledged, one sees that Twitch of the Death Nerve is in fact a variation on Agatha Christies novel Ten Little Niggers/Ten Little Indians (1939) about a group of people on an island being killed off by a member of their group. The Agatha Christie book has been filmed several times as And Then There Were None/Ten Little Indians (1945), Ten Little Indians (1965), And Then There Were None (1974), Ten Little Indians (1989) and And Then There Were None (2015). This leads to the interesting suggestion that the origin of the slasher film then must lie in the Agatha Christie play.
