Biography
Canadian actor John Colicos has often been mistaken for Jay Robinson (who played Caligula in The Robe). Such gaffes are understandable, since Colicos, Zerbe and Robinson have spent their professional lives essaying the same sort of smirking, posturing megalomaniacal villains. Colicos played the demented Mikos Cassadine, plotting to take over the world with his weather-controlling machine during an early-1980s story arc on the TV serial General Hospital? A nicer but no less abrasive John Colicos could be seen playing foredoomed restaurant owner Nick Papadakis in the 1982 remake of The Postman Always Rings Twice. ~ Hal Erickson, All Movie Guide
He is mentioned in The Kenneth Williams Diaries, where the acerbic British actor/comedian mentions how impressed he was by the performance of the young understudy who took over a stage performance as King Lear when the aging, alcoholic star name who was supposed to play the role was unable to perform (Colicos is identified in the index, not Williams' diary entry).
He has the distinction of being the first Klingon commander seen in the Star Trek franchise. He also appeared in countless episodes of episodic television throughout the 1960s, most notably portraying the villain on no less than three episodes of Mission: Impossible. He appeared in four episodes of the eight-episode CBC docu-drama The National Dream, as the "railway general", William Cornelius Van Horne. Several years after his Battlestar Galactica tenure, Colicos again ventured into science fiction. He portrayed power-mad Mikkos Cassadine, a demented scientist bent on freezing the world on the ABC soap opera General Hospital during the height of the "Luke and Laura" frenzy. He also was the voice of the X-Men villain Apocalypse in the animated FOX series in the mid-nineties, and twice played rogue alien Quinn in the first season (1988-89) of War of the Worlds.
