Princess Gwendolyn
One major plot point is never wrapped up in this film. What becomes of Princess Gwendolyn? The last we see of her, she is again threatening Mildred Natwick with death if anything happens to Danny Kaye. Then she disappears. Shouldn't there have been some sort of closure where she decides to marry Robert Middleton after all or enters a nunnery or falls for the REAL Black Fox?
What would YOU have happen with her?
