Movie Info

A family's murderous battle over some bayfront property is the subject of director Mario Bava's bloody horror-thriller, which many have cited as the grandfather of the modern slasher film. Claudine Auger is the scheming daughter of a murdered Countess; her staged suicide forms the basis of the film's plot. In a seemingly unrelated subplot, four hippies arrive in a dune buggy led by Brigitte Skay, who dances the Shake and swims naked before having her throat hacked open with a machete. Skay's

A typically useless effort from Mario Bava...

If only one-hundredth of the films it influenced had one-hundredth of its perfection, the horror film would be a much less disreputable and more wonderful thing than has been the case.

Bava displays how ahead of the curve he was in tackling the slasher genre.

Bava ... uses the scenario the way a virtuoso musician uses a simple chord progression as an accompaniment for an inspired solo ...

July 4, 2008 Full Review Source: ESplatter

Contains some of Bava's finest, and most naturalistic work as well as some innovative gore effects.

You'll see things that countless horror films have stolen, but unlike a lot of classic films that have been ripped off for years, this one holds up.

Audience Reviews for Reazione a catena (A Bay of Blood) (Twitch of the Death Nerve)

Horror Icon Mario Bava crafts a stunning horror feature with A Bay of Blood. Italian directors have long been masters of horror, and Bava who helped pioneer the Giallo, Slasher genres, delivers one of the genre's finest films with this picture. A Bay of Blood is a gory thrill ride that will definitely appeal to gore hounds. The film's plot is simple, yet has enough intrigue to keep you on the edge of your seat from start to finish. The film's atmosphere is dark and brooding, and Bava effectively uses that to his own advantage in order to create a horrifying experience that will stay with you. The ideas here are simple, yet the film works very well due to the fact that the kill sequences are inventive, shocking and memorable. If you love the genre, definitely give A Bay of Blood a shot, this is among the finest of all Slasher films produced, and it is an iconic picture that has a profound impact on many other films that would follow. The film is a terrific display of special effects, and it still holds up to this day. The plot, acting and everything else are good, but the way the killer dispatches his victims is really key of the whole movie. The real star of the film of these sequences that are very well done, and are obviously what makes this film so good. Mario Bava brings a great sense of style to what mainstream viewers would call mindless murder and mayhem. A Bay of Blood is a masterwork of the genre, a milestone in Slasher films and Giallo alike. The cast are good, but in regards to the big picture, the kills are the best aspect of the film and with that being said will surely thrill diehard genre fans.

Ending was good, but movie has way too many characters and is unnecessarily confusing for a horror. Dub is crappy too.

Fantastic early slasher film from the great director, Bava. It starts out mysteriously, confuses you, and then twists things around until it gives you a crazy ending. I loved the blood and gore too, it's perfect. It's only some of the actors who aren't very good, but it doesn't matter. I really enjoyed this.

It just goes to show that the most influential movies are not necessarily the best; this one spawned Friday 13th and a whole host of slasher movies, and yet it's the weakest giallo of Bava's I've seen to date. With thirteen murders and five different murderers running around, no matter how high your tolerance for the ridiculous, sooner or later this movie is going to tip over into farce, though if you're anything like me you'll be too bamboozled by the plot - or lack of it - to pinpoint exactly when this happens. A shame really because things get off to a brilliant start with bravura double murder which breaks the first rule of the giallo, by revealing the killer's identity, then blindsides us with a stunning surprise while we're still catching our breath. I read somewhere that Bava enjoyed working with Laura Betti so much on Hatchet for the Honeymoon that he came up with Bay of Blood purely as an excuse to work with her again. This may well be true but the fact remains that Betti, so good in ...Honeymoon (as the wife who comes back from the dead to haunt the husband who murdered her), is totally wasted here; her fake medium is the most trivial character in the film. A movie with very little to recommend itself besides its bloodthirstiness, although the violence here lacks the sadistic cruelty of Blood and Black Lace and is less striking for that reason.
