51.) Mardi Gras Massacre
A slasher whose killer performs ritual murder on women during Mardi Gras in New Orleans is ultimately pretty repetitive. The victims get their stomachs split open and organs removed so often, with low budget effects, that it becomes tedious after a while. But it’s precisely for that reason that it was successfully prosecuted and banned. The film was never resubmitted to the BBFC for a re-release and thus remains without release in the UK. It was released uncut in the US, however.
