All these people commenting with how "cute" and "cuddly" and "squishable" Martin Freeman!Watson is best watch their backs... He is the angriest mother fucker around, he is NOT cuddly, he is NOT your best mate, and he is NOT afraid to let you know! Ben got to handle an actual functioning gun in episode three, but I wouldn't be at all surprised if Martin Freeman's was a fake. You don't just hand a man like that a loaded weapon without taking excessive precautions as to your own safety.
Continuing from ~trottle-a-swan's not-funner-but-just-as-fun (let's not bump side-character Benny above lead role and also angriest mofo Martin) fact: Not only is Ben voicing (and acting! Motion capture, brah! Dude gets to be a fuckin' dragon legit!) Smaug, but he ALSO gets to be Necromancer, that silly little dude who becomes Sauron.
