Is Tudyk really that famous, or does he just have a particularly loyal following from his collaborations with Joss Whedon? Whedon's work is known for its rabid fans. I've seen Tudyk on stage in a few plays and found him to be a limited actor -- handsome and likable but usually quite flat. Shamos is a major improvement in my eyes.
"You travel alone because other people are only there to remind you how much that hook hurts that we all bit down on. Wait for that one day we can bite free and get back out there in space where we belong, sail back over water, over skies, into space, the hook finally out of our mouths and we wander back out there in space spawning to other planets never to return hurrah to earth and we'll look back and can't even see these lives here anymore. Only the taste of blood to remind us we ever existed. The earth is small. We're gone. We're dead. We're safe."
-John Guare, Landscape of the Body
