Arthur Martinez in Theatre Group's production of Tiny Tim is Dead A student of University of Colorado at Denver, Metro State and many other fine colleges in the metro area, Arthur has had the pleasure of acting with many theatre and film companies around Denver. He has played roles from neurotic to exotic and just downright strange; and somehow he is becoming a better person because of it. Arthur was most recently seen in 12 Angry Jurors, Twentieth Century and The Day Ricardo Falcón Died.
