Starting with a little violence and a particularly sleazy air, Massacre initially feels like a remake of Franco's Barbed Wire Dolls, but with a real director. Unfortunately Bruno Mattei skimps on the lesbianism and full frontal nudity, and settles for a tired, formulaic siege film.
Starring Laura Gemser, the film is, in name only, unofficially part of the Black Emanuelle series, but severely lacking the style that Joe D'Amato, especially, bought to the better entries, such as Emanuelle in America. For a film featuring Gemser, along with exploitation regulars such as Lorraine De Selle, Gabriele Tinti and Carlo Di Mejo, the acting is uniformly dire, with Gemser in particular almost catatonic.
For fans of Gemser, Mattei and Women in Prison films, there are far better examples out there, but Massacre wins an extra star for the sight of Tinti, splattered in blood and brains, shouting "You slut!" during a fraught game of Russian Roulette.
Using a similar setting, and practically the same cast, Mattei had previously directed the far superior Violenza in un carcere femminile. Its probably better to stick with that.
