Exactly I pictured a big curly mustache and not to say we wont see a wild multi-color patched cape but I always pictured more of an exuberance to him. As long as he's got some on screen personality though, I'm here for it!
(From the "We're pulling back the fabric of the Pattern to give you a glimpse into the building of our world." Instagram post today.) He looks very interesting...actor definitely looks younger than I pictured the actual Thom.
