 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".
