I saw Burn After Reading this weekend. Here's my character summary:
Brad Pitt is awesome and hilarious.
Francis McDormand is neurotic and ridiculous.
George Clooney is obsessive and wimpy.
Tilda Swinton is a bitch.
John Malkovich is a freaky, scary loser.
And that about sums it up. If you like the Coen Brothers, you will probably like this movie. I thought it was GREAT.
