4567, James Stewart wasn't in "Three Comrades", that did have Robert Young, also Robert Taylor and Franchot Tone. Yes, it was sad at the end with both Margaret Sullavan and Robert Young dying. I agree, James Stewart and Margaret Sullavan had good chemistry. Stewart actually had strong feelings for her offscreen, but she ended up marrying his best friend, Henry Fonda. James Stewart and Margaret Sullavan also starred in "The Mortal Storm" and "Shopworn Angel". Very good films.
