Paul Allen Ballard is a freelance illustrator who does all sorts of awesome stuff including sketch cards, collectible card game art, Star Wars promotional stuff, and the thing that really grabbed my attention, the covers for the comic book Zombies of Mass Destruction. They could each be a movie poster. I would hang each of those covers on my wall, especially number 3. Zombies of Mass Destruction is written by the creator of the Underworld movie franchise, and has itself been acquired for movie rights. It's about zombies being used as WMDs, which I personally think is a fantastic idea.
Check out Paul's blog for higher res images of those awesome covers. Thanks for the amazing sketch/painting, Paul!
