Thanks a Million is a 1935 musical film produced and released by 20th Century Fox and directed by Roy Del Ruth. It stars Dick Powell, Ann Dvorak and Fred Allen, and features Patsy Kelly, David Rubinoff and Paul Whiteman and his band with singer/pianist Ramona. The script by Nunnally Johnson was based on a story by producer Darryl F. Zanuck (writing as Melville Crossman) and contained uncredited additional dialogue by Fred Allen, James Gow, Edmund Gross and Harry Tugend.
Thanks a Million was nominated for the Academy Award for Sound (E. H. Hansen) in 1935. It was remade in 1946 as If I'm Lucky, with Perry Como and Phil Silvers in the Powell and Allen roles.
