Cristina Ferrare is the title slasher villain/vampire in Mary, Mary, Bloody Mary which is a pretty solid entry in the genre. In fact I was reminded of both Martin and The Velvet Vampire as well. The murders in this movie happen fairly quickly and Mary is being followed by an eerie stranger (horror legend John Carradine) who may have a link to her bleak past. I won’t say more, just that despite being goofy at times I was fairly engrossed in this flick and I rather liked it a lot despite the obvious B-movie limitations.
David Young is also great as the caring boyfriend who of course has no idea his special lady has a thirst for blood that is never ending. Juan López Moctezuma even throws in a frantic and wild car chase for good measure, just to pad out the movie. I think 1970s campy vampire movies are among my favorite things from the decade at this point.
