Early in 1942, he was ordered to military active duty in San Francisco and never became a true film star. After his wartime military service he co-starred in such films as The Voice of the Turtle, John Loves Mary, The Hasty Heart, Bedtime for Bonzo, Cattle Queen of Montana, Tennessee's Partner, Hellcats of the Navy (the only film in which he appears with Nancy Reagan), and the 1964 remake The Killers (his final film). Throughout his film career, Reagan's mother answered much of his fan mail. In 1946, Reagan served on the national board of directors for the Independent Citizens Committee of the Arts, Sciences and Professions (ICCASP) and had been a member of its Hollywood chapter. Four decades later it was revealed that, during the late 1940s, Reagan (under the code name T-10) and his then-wife, Jane Wyman, provided the FBI with the names of actors within the motion picture industry whom they believed to be communist sympathizers.
