Torn Curtain
Though Mills did much television work, he also found regular work in motion pictures. He is probably best known as the suspicious highway patrolman who follows Marion Crane (Janet Leigh) in Alfred Hitchcock's classic thriller "Psycho" (1960). A few years later, he worked again with Hitchcock, playing a spy in East Germany under the cover of being a farmer in "Torn Curtain" (1966). Mills also appeared with Charlton Heston in Orson Welles's "Touch of Evil" (1958).
