As for Just talent, and not looks I choose

Michael Emerson

aka. Ben Linus, Henry Gale

Loved his acting in the episode "The Man Behind the Curtain"
The best episode of lost so far imo

Also loved in on the season three trailer when he says "Without warning, they fell from the sky. They stood together, Fought together, Endured together. They were free from the world. Free from their past. They finally have a chance to discover who they really are. And what could be more terrifying, then that."

He has an awesome creepy voice, one of my all time fav actors!
