Yes, indeed, that PROMETHEUS trailer rocks. But Fox isn't done yet, apparently - it also debuted the new ABRAHAM LINCOLN: VAMPIRE HUNTER trailer as well. And I'm sold. This isn't tongue-in-cheek stuff - Timur Bekmambetov is playing it completely straight, and I think that's what makes everything I've seen so far work so well. WonderCon showed the new trailer, but here it is online in all its glory. There's an IGN watermark on it, but I can't find the link to credit them on their site, so visit IGN when you get the chance, okay?
