The Real reason James Stewart died 1 or 2 days after Robert Mitchum..it was a Vengeance Vendetta. In 1978 the starred in british film called 'The Big Sleep' sort of Philip Marlowe-esque detective film..with British peep-show plot. Jimmy Stewart, dedicated fine actor he was vowed never to start in a film with nudity. Mitchum didnt give a crap, every woman & actress desired the rough, brawn image of Mitchum. To Satisfy British audience gate attraction draw..the film director required female frontal nudity (Candy Clark...of "American Graffiti, blonde air head actress") which top British poplarity Mitchum's influence over-ruled James Stewart disagreements. Stewart obviously vowed to get even with Mitchum 'in death' and die 1 or 2 days afterwards in the future, whenever that day arrived. Hence, Jimmy Stewart could rest assured he acting legacy tributes would 'outshine Mitchums legacy tributes'. Weird as it sounds. Listen here, the USA military might respected Mitchum's over the top war film bravado bravery courage and arrogance alot more than the Touchy Feely sometimes Wimpiness of Mr. Stewart, eventhough Stewart rose to the rank of Lt. General in the US AirForce.
