James Stewart did this guest shot as a favour to pal Fred MacMurray, although they don't share the screen together. When World War II came along, Stewart, who was a qualified pilot, enlisted in the U.S. Air Force and saw action in the skies over Germany. He won the highest decoration for bravery and attained the rank of Colonel (religiously sending his agent monthly cheques for 10 per cent of his wages, which amounted to $2.10)! Stewart retained his commission in the Air Force Reserve and, in 1959, attained the rank of Brigadier-General. He was the first member of the Air Force Reserve to reach General rank and attained the highest rank of all the WWII-vintage members from the entertainment industry to have served in the military. He retired from the Air Force Reserve in 1968. He died in 1997, aged 89, a much loved member of the Hollywood community.
