After being refused admission to the U.S. on the grounds of his unsavory reputation following a European trip in 1952 (again the work of Hoover, whose file on Chaplin was 1,900 pages long), Chaplin and Oona settled in Switzerland.He continued to make films sporadically until 1967 (working with such talents as Claire Bloom, Marlon Brando and Sophia Loren).
