Because I had never actually seen The Beast Must Die, I didn't recognize its clear influence on last year's Werewolves Within (a film a enjoyed a lot). I also didn't know that the film's star was not Peter Cushing, as I had assumed, but Calvin Lockhart, (Cushing's role is much smaller).
That casting helps elevate the movie above its clear Hammer influences and into something a bit more interesting. It's not quite in the realm of Blacksploitation horror - it's a much better movie than something like Blacula - but having a Black couple at the center of the story (Marlene Clark, who was in a film I featured last year, plays Lockhart's wife), makes it a lot more interesting than your standard 70's horror flick.
The film famously features a 30-second "werewolf break" asking you to guess who the werewolf is before the final reveal. I wonder if people actually screamed out their answers in the audience when this movie was originally released?
I watched The Beast Must Die on TCM, but it is available to stream on several platforms, including Tubi.
