[Martin’s] most remarkable quality as an actor is to be able, with absolute clarity, to convey that he’s thinking two things at the same time, and you know as an audience what they are. And I wasn’t the only one on set to say later, “I wish I could act like that.” Martin Freeman has a palette of subtlety, and I thought, this is a new sort of acting that I’ve never seen before. – Ian McKellen, The Hobbit Behind The Scenes

He really is that good.

And it’s so phenomenally understated.  It’s so natural, you never even notice how he’s blowing your socks off.
