Dear Ruth is a 1947 romantic comedy film starring Joan Caulfield, William Holden, Mona Freeman, and Edward Arnold. It was based on the 1944 Broadway play of the same name by Norman Krasna. A teenage girl has a soldier for a pen pal, but uses her older sister's name and photograph. Then the man shows up while on a two-day leave. There were two sequels: Dear Wife (1949), with all of the principal actors reprising their roles, and Dear Brat (1951), featuring Freeman, Arnold and De Wolfe.
