The working title of this film was Love Song. Lily Pons made her screen debut in the picture. According to the MPH review, the film, which ran 95 minutes in a preview screening, was to be cut. Post-release reviews and the copyright entry differ significantly on the films' length, however, and it is unclear whether RKO ever made the projected cuts. RKO borrowed Henry Fonda from Walter Wanger's production company for the film. According to one review, the lyrics for "I'm the Echo" were taken from a poem by Dorothy Fields. HR production charts add Betty Grable, Reginald Barlow, Paul Irving, Oscar Apfel, Kay Sutton, Billy Gilbert, Henry Hanna, Dewey Robinson, Edgar Norton, Ferdinand Gottschalk, De Witt Jennings and Jane Hamilton to the cast, but their participation in the final film has not been confirmed. According to a HR news item, Natale Carossio, the stage manager of the San Francisco Opera Company, was assigned to "assist" in the filming of this picture. The exact nature of his contribution has not been determined. The film was nominated for an Academy Award in the sound recording category.
       A biography of Jerome Kern gives the following production information: When Kern agreed to write music for the film, he demanded that Fields be his lyricist and then demanded that Robert Russell Bennett orchestrate his music instead of RKO music director Max Steiner. Pons, in turn, insisted that Andre Kostelanetz conduct her operatic arias. (Pons and Kostelanetz were married from 1938-1958). Kern was paid $5,000 per week by RKO, while Fields earned $1,000 per week. On 18 Sep 1935, producer Pandro Berman wired Kern that he was changing the title from Love Song to I Dream Too Much in order to exploit what Berman believed was to be the film's hit song. Berman encouraged Kern to promote the song as much as possible prior to the film's opening. In his autobiographical writings, Oscar Levant states that he helped out on some "technical details" on this film as an outgrowth of his "hero-worship" for Kern.
