James Whale's high quality version of Dumas's classic tale of twin brothers, one the king of France and the other a prisoner at Isle St. Marguerite (Hayward, very fine in a dual role). William, as musketeer D'Artagnan, comes to the aid of the imprisoned brother, who is mercilessly forced to
wear an iron mask to prevent anyone from realizing he is heir to the throne. Whale directed this elaborately costumed adventure with the greatest of verve and flair, though his career came to a halt in 1941. (Aging and frail, the master director committed suicide 16 years later.) This film also
marked the first screen appearance of Peter Cushing.
