Later, Bellamy would reprise his role as FDR in this mini-series' sequel, War and Remembrance (1988).

Robert Mitchum was accused of anti-Semitism and Holocaust denial after an interview he gave to Barry Rehfeld of "Esquire" magazine promoting this series at his home in February 1983. Mitchum wrote an apologetic letter on 9 March 1983 to Herbert Luft, the Jewish Telegraphic Agency's Hollywood columnist. Mitchum claimed he had recited views expressed by the bigoted football coach he had played in That Championship Season (1982), which Rehfeld "mistakenly believed to be my own. From that point on, he approached me as the character in the script and in playing the devil's advocate in a prankish attempt to string him along we compounded a tragedy of errors." Mitchum added he was "truly sorry that this misunderstanding has upset so many people, especially since it is so foreign to my principle. The attendant misfortune is that it has brought me a spate of mail from people and organizations who are encouraged to believe that I share their bigotry and discrimination.".
Aaron Jastrow (John Houseman) mentions that the correct Polish pronunciation of his family name would be "Yastrov."

Adolf Hitler specifically forbade aerial attacks on either the UK itself or on the Royal Navy on 25 January 1940 unless the British bombed Germany first.
