This lengthy Billy Wilder yarn about Charles Lindbergh and his famed cross-Atlantic flight has always stuck in my head mainly for the film’s second act. In particular, James Stewart’s one-man show from the hour mark on, aside from the moments he shares on screen with a fly, always fascinated me. Only later did I discover that the 47-year-old actor was portraying a 26-year-old aviator — and the audience never flinches.  How’s that for actorly chops? I didn’t see this frequently with the old man but I vividly recall the first time it crossed my bow when he set the remote aside and stopped flipping channels for a few hours.
