Factual error: The song "I Won't Dance" was not written until the early-'30s, at least six years after the time it was shown being used in the film. However, it is still performed in the dining room scene.
Factual error: In the early scenes of the movie, before Franklin Roosevelt contracts polio, he is seen dancing with his private secretary to a recording by Alice Faye of the song "I'll See You In My Dreams". The song was not written until 1924, more than a year after FDR contracted the disease, and Alice Faye did not record it until 1939.
