Martin Freeman, The Hobbit. I totally agree with Peter. Martin is *the best* person ever to play Bilbo. Not only does he embody what it means to be a hobbit very well, but he also has the quirkiness and humor of Bilbo himself.
Dean O’Gorman (Fili) and Aidan Turner (Kili) needed 47 takes for this scene because they didn’t manage to bow at the same time. And because Martin Freeman was behind the camera making faces. And Kili said that he was Fili and Fili said he was Kili.
The Hobbit - The infamous egg toss while sitting at the table in Bilbo's dinning room was real, not CG. That's why the reactions of everyone at the table are so awesome, they weren't acting, their reactions were completely genuine!
