Though the film shows the Roosevelts visiting Franklin Roosevelt's secretary Marguerite "Missy" LeHand following her collapse and subsequent stroke, in fact, Franklin Roosevelt never visited LeHand after she fell ill, most likely due to his emotional and psychological inability to deal with others to whom he was close who were ill or dying, which is explained in an earlier scene in which Eleanor visits the dying Louis Howe, Franklin Roosevelt's political advisor.
When the Roosevelts travel back to the White House after FDR's second inauguration, on January 20th, 1937, the trees are full, with green leaves.
In the opening, set in 1905, when a horse carriage enters the White House drive, modern automobiles are visible across the park.
