With regard to Hollywood's role in WWII, I just saw a documentary on the great director John Ford. It was Ford who basically made John Wayne's career. Ford spent time in the war filming combat in the Pacific. Supposedly he hardly even spoke to Wayne during the war because he was upset that Wayne did not serve. As for boxers in the war, Tunney, Dempsey, Baer and Barney Ross who was decorated for valor at Guadalcanal. Apologies for anyone I've letf out.
