This one was originally called Dracula, but the title was changed for the U.S. market to avoid confusion with the Bela Lugosi version. (It was also released here on a double feature with The Thing That Couldn't Die.) It was Hammer Films' first of several Dracula movies, and an early example of Hammer Horror, coming a year after The Curse of Frankenstein.
Hammer was a staple of Creature Feature shows when I was growing up. You looked forward to them, because even the worst of them didn't suck the way something like The Corpse Vanishes did. Their Dracula had a lot going for it. Christopher Lee seemed born to play the title role ... eventually he played the Count ten times, seven of those for Hammer. Peter Cushing, another Hammer warhorse, played Van Helsing. The two had also starred in the Frankenstein movie, with Cushing as the Doctor and Lee as the Monster.
Hammer added decent production values to the horror genre, albeit with low budgets. They looked good, especially once we got a color TV. The best ones are the earliest, which were taken seriously both by the filmmakers and critics, at least as far as critics could go with the genre. (Dracula is #896 on the They Shoot Pictures, Don't They list of the top 1000 films of all time.) Eventually, the budgets seemed to be smaller, and a certain camp quality crept in. (I remember watching Dracula Has Risen from the Grave once in a theater where the audience laughed throughout the picture, prompting the man in charge to stop the film and come out to berate the audience.)
Dracula isn't nearly as gory as you might expect. Hammer is known for adding more overt sex to their movies, and while censors in 1958 weren't going to allow much, Lee was clearly a much sexier vampire than Lugosi, and the scenes where he bit buxom women were sexy in ways you didn't see in 1931. There's a story about director Terence Fisher telling one of those actresses, Melissa Stribling, "Just imagine you've had the best sex of your life, all night long!"
The picture is rather slow, to be honest. Lee only appears on the screen for seven minutes. The atmosphere is appropriately unsettling, and Lee and Cushing are great. It's far from the worst Dracula movie you'll ever see. But neither is it a classic.
I'll mention a couple of other Hammer pictures. Quatermass and the Pit (released in the States as Five Million Years to Earth) may be my favorite, and I'm surprised I've never written about it. And there is no better example of how loosening censorship gave Hammer space for more sex than 1970's The Vampire Lovers, which did get a blog post after I bought it on Blu-ray.
