Horror of Dracula is a delight from start to finish. The sets are lavish, the script is well written, the soundtrack is effective and the acting is superb. Basil Rathbone is flawless as Dr. Van Helsing. He gives what I think is the best performance of this character in any Dracula movie. It's so good, in fact, that Van Helsing rather than Dracula commands center stage in this film. Christopher Lee gives a solid performance as Dracula, although I think that Bela Lugosi did it better in Dracula (1931). Both Carol Marsh [Lucy] and Valerie Gaunt [Vampire Woman] give enthusiastic performances as the recently undead. They look like wide-eyed children on Christmas morning as they wait for the Prince of Darkness to arrive.
Horror of Dracula is one of many successful movies from Hammer Film Productions which is based in the United Kingdom. From the mid-1950s to the 1970s Hammer was one of the kings of horror and dominated the market during their most successful years. Surprisingly, these films had low budgets which goes to show you that money does not a good horror film make.
This film can be viewed in nine parts on YouTube. You can also watch it instantly on Netflix or rent it as well. Horror of Dracula is one of the best vampire films ever made. Don't miss it! It's a good old fashioned horror.
