Jamie Horton, one of the earliest members of the Denver Center Theatre Company, is a local treasure. He proved it again this year with his performance as Dalton Trumbo in Curious's Trumbo: Red, White and Blacklisted, making the man eccentric, outspoken, wise and wily in that peculiarly evocative American way. Horton also shone in The Misanthrope at the Denver Center. And he was almost the only actor on stage with sufficient power and presence to project a distinct personality through the speech-muffling masks of the DCTC's Oedipus Rex.
