This prolific stage-trained character player has been a familiar face since the early 1980s. With his bald head, deep-set eyes, and richly expressive features, Picardo has portrayed a wide range of characters on TV: most notably, a cold-hearted junior high school gym coach--the dreaded Coach Cutlip in a recurring role on "The Wonder Years" (ABC, 1988-91); a dedicated and sympathetic military surgeon (and the beloved of nurse Dana Delany) in wartime Vietnam on "China Beach" (ABC, 1988-91); and a somewhat testy but supremely competent holographic ship's doctor on the spin-off "Star Trek: Voyager" (UPN, 1995-2001). The latter gig would appear to be the actor's best shot at pop culture immortality. Picardo's prior roster of guest shots and short runs included "Benson," "Dinosaurs," "21 Jump Street" and "L.A. Law."
