excellent method of escape, just be sure not to go near any forests, becuase if one of those zombies decides to eat a rat or a dog. Then you have the entire animal population to worry about. I haven't done the zombie research, but how does a zombie die of starvation? Aren't they already dead? I know that they need to eat to give them strengh, and that the flesh does not fuel them for long, but in any case, I think that they would just collapse, and conserve energy for a later strike, like in the Resident Evil game where zombies will try to eat your legs as you walk by.
I hope this movie does well. More zombie movies = more fun. It's also nice to see Sarah Polley doing something that isn't boring.
