Decent Hammer film, but no more than that. Oliver Reed plays the title character ... he only got second billing, though, and was paid only £90 a week. Of course, he doesn't even turn up until halfway through the movie, so maybe the billing and the paychecks were appropriate. Probably the most interesting other person in the cast was Anthony Dawson, who was a bad guy in 3 of the first 4 Bonds, twice as Blofeld.
This is the only werewolf film made by Hammer Studios. It was also the first werewolf film to be shot in color. It looks OK, as most Hammer films did. As I said about The Brides of Dracula, "the Hammer films were a step above the usual" for late-night Creature Feature TV shows. But this fact, plus the presence of Oliver Reed (who admittedly makes a good werewolf), don't make The Curse of the Werewolf into a good movie. It drags, especially during the first half, and characters that seem important disappear later in the film. Worst of all, the film takes place in "Spain", so while everyone speaks with a British accent, their names are Don Alfredo and Leon and Christina Fernando. Once in a while, someone calls someone "Señor," and it sticks out like the proverbial sore thumb.
