The Iron Mask, rich in breathtaking swordfights, carefree merriment, and suspense, is one of Douglas Fairbanks, Sr.'s masterpieces. The story of the four musketeers, gentle Athos, jolly Porthos, brave Aramis, and fearless, outgoing D'Artagnan, goes on in this tale of twin heirs and the unscrupulous Count de Rochefort who switches them to obtain his own ends.
