The second Charles and Diana movie, with two virtual unknowns in the leads: Christopher Baines had acted on the British stage and on the BBC, but Catherine Oxenberg, a U.S.-born, British-raised professional model, here made her acting debut. Of particular interest was the casting of Dana Wynter as Queen Elizabeth, Stewart Granger as Prince Philip, Olivia de Havilland as the Queen Mother, and Ray Milland as a general factotum around the Palace.
