Selmer Jackson is in studio records playing "Mr. Baxter", but he was replaced by Charles Trowbridge. Also in studio records as "Mason" was Vinton Hayworth, but he was not seen in the print. The Hollywood Reporter listed Samuel S. Hinds and Emma Dunn in their usual roles as Dr. Kildare's parents, but they were not in the film either. These omissions may have resulted from final cuts, since the preview time listed in Daily Variety was 100 minutes.
When Lew Ayres announced he was a conscientious objector to the war shortly after the film was released, hundreds of bookings were canceled because of protests. Loew's ordered that all cancellation requests be granted. When Ayres changed his status (in April 1942) to "non-combatant", many in the film industry stated that a boycott of his films would be intolerant and inconsistent with "Americanism".
