He looks amazingly like Michael Fassbender and Lee Pace and while I do enjoy the curly blond hair, I kind of enjoy him more with the black hair he sported in Thor. In a few of those icons he looks like a guy I work with, it's a definite uncanny resemblance.
And wow that was a bit of a ramble. These are good icons, I'm bookmarking so to use at a later date :)
