I'm a bit late in responding to this one (sorry!) but thanks for the review. I started watching this movie on TV when I was a kid (back when they used to show good old horror flicks), but for some reason turned it off about 15 minutes in. Having forgotten the title, I have spent the intervening years wondering what this movie was! When I read your description of the beggar and the prince who locks him up, it all clicked!Monterey Jack wrote:-The Curse Of The Werewolf (1961)
I remember the title sequence of this film being particularly creepy, with its close-up of the monster's teary eyes (maybe that's why I turned it off!).
