Vivien Leigh is even better in this film than she was in GONE WITH THE WIND. She has a fragile, hunted beauty which works perfectly for her role as the unwilling spy forced into romantic entanglements and deceptions. The story is murky, but that doesn't really matter. Watch the sequence where Vivien has been marched aboard ship and locked into her stateroom for deportment as an unwanted spy. Using just her eyes and her expression, Vivien does an entire scene of tossing in her sleep, going to the porthole, and lying back down to sleep again, showing every emotion from fear, suspicion, and doubt to acceptance of her own guilt. Then there's an explosion and she sits bolt upright, looking as fragile and unspeakably lovely as a hunted deer. This is a movie where the sheer radiance of the lead actress makes everything else seem dull by comparison.
