Once Upon a Mattress

The 2005 made-for-television musical comedy film "Once Upon a Mattress" stars Carol Burnett as Princess Winnifred, whose arrival at the kingdom sets off a series of events that challenge the rules set by Queen Aggravain and her son Prince Dauntless. Lady Larken (Tracey Ullman) is pregnant and hopes to marry Sir Harry, who brings back Winnifred after searching for a suitable bride. The Wizard helps Aggravain with a test designed to find a "genuine" princess, but Winnifred's sensitivity and kind heart ultimately win over the prince and his mother.
