Koenigliche Hoheit (His Royal Highness) was adapted from a novel by Thomas Mann -- who, according to all reports, was pleased with the film version. Ruth Leuwerick stars as an American heiress raised in Europe. She falls in love with Dieter Borsch, a handsome but shy German prince. Their romance seems doomed when Borsch is obliged to enter into a marriage of convenience to save his country from bankruptcy. A fortuitous 11th-hour plot-twist prevents the film from being merely another variation of The Student Prince. Contemporary viewers felt that Koenigliche Hoheit might have benefited from a lighter directorial touch than the one displayed by Dr. Hans Braun. ~ Hal Erickson, Rovi
