The Man in the Iron Mask is a 1998 adventure film[2] directed, produced, and written by Randall Wallace, and starring Leonardo DiCaprio in a dual role as the title character and villain, and Gabriel Byrne as d'Artagnan. It uses characters from Alexandre Dumas' D'Artagnan Romances and is very loosely adapted from some plot elements of The Vicomte de Bragelonne. The film centers on the aging four Musketeers; Athos, Porthos, Aramis, and D'Artagnan and the reign of King Louis XIV of France. It attempts to explain the mystery of the Man in the Iron Mask, using a plot more closely related to 1929 Fairbanks' version, The Iron Mask, and the 1939 version by James Whale than the original Dumas book.
