In 1872, Dracula was finally put to rest by Professor Van Helsing. One hundred years later, a group of young people thinks it might be good for a few laughs to perform a Black Mass. Unknown to them, a member of their group is a decedent of one of Dracula's disciples who has been waiting for this opportunity to bring Dracula back from the dead. Alive in modern day London, Dracula now seeks revenge against the Van Helsing family and plans to get that revenge by making Jessica Van Helsing one of his kind.
Take a look around the internet and you'll notice that on almost every list of favorite Hammer vampire films, Dracula A.D. 1972 is at or near the bottom. I don't get it. I actually had a bit of fun with this one. The scenes of the Black Mass were sufficiently creepy, much of the hip 70s music and vibe were infectious, Stephanie Beacham made a great heroine as Jessica Van Helsing, Christopher Neame was perfectly cast as Dracula's disciple Johnny Alucard, and the final showdown between Christopher Lee and Peter Cushing is one of the better match-ups they had in these roles. I enjoyed it so much that I have no problem placing Dracula A.D. 1972 among my three favorite of Hammer's Dracula films.
It just goes to prove that while recommendations on the internet can be useful, taking a chance on a movie with a less than stellar reputation can sometimes payoff.
