According to
Richard Rodgers,
George M. Cohan deeply resented having to work with Rodgers and lyricist
Lorenz Hart on the film. Cohan was bitter that the type of musical theatre that he had created was now out of fashion, and that it was being supplanted by the more literate and musically sophisticated shows of Rodgers and Hart, among others. During the filming Cohan would sarcastically refer to Rodgers and Hart as "Gilbert and Sullivan".
