Sam Worthington is the grizzly veteran who's done it all before. Jonah Hill is the annoying n00b who inevitably steps on the land mine and uses an RPG to shoot a sniper in the back. Anyone who has played Call of Duty, or any other online FPS, will undoubtedly recognise both types of player. With an awesome soundtrack to boot if this trailer doesn't make you want to play Modern Warfare 3 nothing will!
