It's interesting, though, when you think about it how pervasive the Three Types of Zombies you mention are. The second type even occurs in places you wouldn't expect it too. The Strangers from Dark City are aliens and intelligent but a major part of what makes them scary is the fact they're wearing human corpses.
In any case, this is a really interesting thread, and I like your stuff Rob.
Thank you, sir. You're a gentleman and a scholar... etcetera.
I do have to contradict myself (or at least my story) to point out that I don't necessarily consider the "outside intelligences controlling human corpses" thing to be a true zombie, because it doesn't have the "mindless" quality I talked about. The thing has
a mind, it's just a foreign mind that's inhabited a vacant shell. For example, The Hidden
(the 1987 sci-fi/horror flick starring Kyle Maclachlan) revolves around a joyriding alien parasite that kills and then possesses human victims, moving from body to body on an interplanetary crime spree. I think it'd be a stretch to refer to that as a "zombie film".
It is, however, an absolutely balls-to-the-wall awesome movie, which is why I had to find a tenuous excuse to bring it up.
