Crosby's effortless baritone, caramel-mellow singing style, and his easy-going, self-mocking charm helped him endure while other, flashier talents faded around him. His escapist material both in song (with mostly a "Sunny Side of the Street/Pennies From Heaven" upbeat philosophy) and in reassuring, sentimental films--"Holiday Inn" (1942), "Going My Way" (1944), "The Bells of St. Mary's" (1945), "White Christmas" (1954) and "High Society" (1956)--helped audiences forget the Depression, WWII and its aftermath and account for his enormous popularity. Although he refused to play screen heavies, in the 1950s Crosby proved his skill as dramatic actor with his complex performance as a washed-up alcoholic singer in "The Country Girl" (1954); he played another alcoholic, this time a doctor, in the 1966 remake of "Stagecoach".
Crosby co-authored an autobiography, "Call Me Lucky" in 1952, but his son Gary's scathing portrait of his father in "Going My Own Way" (1983) revealed a stern, unloving disciplinarian contrary to Crosby's easy-going public image.
