Even though Bela's movies are "before my time," I can't help but appreciate his roles in these low budget flicks of yesteryear. I love the premise of this movie and can see a modern variation on this theme of giant bats that "sever the jugular" of their victims.As a warning to all, do yourselves a favor and only buy the one which states that the movie was released by the Bela Lugosi Estate since this version uses the original film elements to present a nice, crisp picture. Bela Lugosi Jr. offers running commentary during the film as one of the Extras. He looks well preserved for his age if you get my drift.Anyway, a fun movie to watch. Don't take it too seriously. After all, it is a 1940s B-Grade horror movie. Just sit back and enjoy the show. And don't forget the popcorn for crying out loud!
