"When he gets out of the Army, which may be soon, Jimmy expects to go back to making movies," LIFE wrote. "'But no war pictures,' he said. 'I'll settle for good comedy.'" True to his word, Stewart returned to film in 1946 -- with a little picture called It's a Wonderful Life. (full photo album of 22 pics)
