What Caliber For Giant Man Eating Japanese Human Monsters?

A trailer for the movie Attack On Titan:

By the looks of the trailer, they mainly like to get up close and personal with the sword work.  Cool.  I’m sure there are plenty of guns in the movie as well.  Anime is so crazy.  It’s like nightmare material, and this is no exception.  Did you see those creepy grins?

This movie definitely isn’t high on my list of ones to see in a theater, but I’m definitely not sleeping on it once I can watch it at home.

Attack-On-TitanSomeone tell me the graphic novel series is a “must read”…. or nah?  Looking at the wikipedia page it must be good, because I see it put up some serious number (45 million volumes in print!).
