Eleanor Powell's first color film and last MGM film.
Eleanor Powell's number for this film was originally shot for "Broadway Melody of 1943," a project MGM abandoned before it was completed. "Broadway Melody of 1943" was to have co-starred Powell and Gene Kelly, who both appear in "Thousands Cheer" but are never seen together.
Some cast members in studio records/casting call lists did not appear or were not identifiable in the movie. These were (with their character names): Connie Gilchrist (Taxicab driver), Daisy Bufford (Maid), Pierre Watkin (Alex), Edmund Mortimer (Guest) and Lionel Barrymore (Announcer). Bryant Washburn Jr. was announced as a cast member, but only his father, Bryant Washburn, had a role in the movie. Gus Schilling was also announced as a cast member, but he was not in the movie either. Barrymore is referenced by a comic impersonation performed by Mickey Rooney.
