I had to go look what I had even seen Martin Freeman in. Other than playing Arthur Dent, not that much. A few small bits here and there. I remember thinking he was pretty good as Arthur Dent but I think I was so generally underwhelmed by the whole Hitchhiker movie - disappointed I think it's fair to say - that his performance maybe got lost? I don't know. I want to watch that again now.
I'm not sure how to even interpret what I am seeing with him in Fargo. I don't know if it's by design or sheer will power on his part but he is keeping his character, which I sense some people might like to shove firmly into the realm of shtick at times, and walking the line and keeping it a real person. But funny. Some of the little passing expressions are priceless.
