And to think, I too could have guessed Hardware if I could have thought of the name, since it was one of the three movies I thought of.
And for some reason this makes me think of either Iggy Pop or vampires. Or Iggy Pop as a vampire.
But, I'm going to guess Blood and Donuts since it's the only movie I can currently think of with a vampire that might eat rats, who isn't played by Brad Pitt...
