At the end of the war, Riskin returned to New York City, where, in partnership with a friend, he found some success in producing plays for
Broadway. Riskin began his career as a playwright, writing for many local New York City playhouses. When the U.S. entered
World War II, he joined the
Office of War Information in 1942, In 1939, looking for creative autonomy unavailable in the studio system, Riskin and Capra formed an independent production company, Frank Capra Productions. The partnership was divided 65% for Capra, 35% for Riskin. In 1941, Capra directed Riskin's
Meet John Doe. However, Riskin felt that Capra was taking all the credit for their films, including Riskin's share. Riskin came to resent Capra for this. This led to several confrontations with Capra during the production of
Meet John Doe. According to an account by Hollywood screenwriter David Rintels (which was denied by Capra), Riskin brandished 120 blank pages in Capra's face and challenged: "Put the famous Capra touch on
that!" After completion of just one film,
Meet John Doe, the association was dissolved. Riskin never willingly collaborated with Capra again. During the time of his declining health, home confinement, and final residence at the
Motion Picture & Television Country Home and Hospital, Riskin was regularly visited by old friends such as
Edward G. Robinson,
Jack Benny, and
Irving Berlin. Long time friend and screenwriting colleague
Jo Swerling and his wife remained devoted visitors. Conspicuously absent was Frank Capra, who never visited Riskin during the five years of his illness. Swerling was pained by Capra's behavior, but Riskin refused to disparage Capra. He remained loyal to the man, calling him "his best friend". The
Los Angeles Examiner covered Riskin's funeral in September 1955, describing the "notables" in attendance. The report also identified the "one man who wasn’t there": Frank Capra. In 1961, Capra directed
A Pocketful of Miracles, a remake of Capra and Riskin's 1933 collaboration
Lady for a Day, with a screenplay by
Hal Kanter and Harry Tugend from the Riskin-Runyon material. Aside from
an industrial film directed for Martin-Marietta in 1964, it was Capra's final effort as a director. ==Personal life and family==
