The 5th Musketeer

An appealing cast of film veterans makes this 1977 action-adventure version of Alexandre Dumas's The Man In the Iron Mask particularly watchable. Lloyd Bridges co-stars as swordsman Aramis, one of several Musketeer tutors of young and brave Phillippe (Beau Bridges, Lloyd's son), who doesn't know he's the identical twin brother of King Louis XIV. Captured by Louis, his features briefly disguised by an uncomfortable iron mask, Phillippe is forced to play his villainous sibling in an assassination scenario designed to fool France into believing its mad emperor is dead.
