Wisconsonite actor Stanley Blystone was the brother of director John G. Blystone and assistant director Jasper Blystone. Entering films in 1915, the burly, muscular, mustachioed Blystone excelled in gruff, villainous roles; he was particularly menacing as a crooked ringmaster in Tom Mix's The Circus Ace (1927). In the talkie era, Blystone was busiest at the 2-reel comedy mills of RKO, Columbia and Hal Roach, often cast as brutish authority figures at odds with the comedy leads. In the Three Stooges' Half Shot Shooters (1936), he plays the sadistic Sgt. McGillicuddy, who reacts to the Stooges' ineptness by taking aim with a long-range cannon and blowing the three comedians right out of their boots! Blystone was much in demand as both "action" and "brains" heavies in Columbia's westerns and serials of the 1940s. Extending his activities to television in the 1950s, the 71-year-old Stanley Blystone was en route to Desilu Studios to play a small role on the TV series Wyatt Earp when he collapsed on the sidewalk and died of heart failure.
