Had a Mario Bava evening both of which i had seen a long time ago and were in desperate need of a re-watch.
Hatchet For The Honeymoon - Though not Bava's best it is a very good little film, half slasher/half ghost film.
A Bay Of Blood - The one that started the slasher genre? This was ahead of it's time and was a major inspiration for later films, with two kills from Friday the 13th Part 2 - being directly taken from this. I read somewhere that Christopher Lee watched the film after being interested in seeing what Bava had recently made after working with him 8 years before (The Whip & The Body), aparently Lee was apalled by the films high violence. I find it quite ironic that one of horrors most famous faces was appaled by violence.
