Martin Miller, born Johann Rudolph Müller was a Czech-Austrian character actor who played many small roles in British films and television series from the early 1940s until his death. He was best known for playing eccentric doctors, scientists and professors, although he played a wide range of small, obscure roles—including photographers, waiters, a pet store dealer, rabbis, a Dutch sailor and a Swiss tailor. On stage he was noted in particular for his parodies of Adolf Hitler and roles as Dr. Einstein in Arsenic and Old Lace and Mr. Paravicini in The Mousetrap. Miller appeared in several notable films, including Squadron Leader X (1943), English Without Tears (1944), The Third Man (1949), The Gamma People (1956), Peeping Tom (1960), 55 Days at Peking (1963), The V.I.P.s (1963), The Pink Panther (1963), and The Yellow Rolls-Royce (1964). His most substantial roles include George II of Great Britain in Bonnie Prince Charlie (1948) and Kublai Khan in the Doctor Who serial Marco Polo. In the 1960s, he appeared in several ITC Entertainment cult television programmes, including Ghost Squad, Danger Man, The Saint, The Avengers and The Prisoner.
