The Man in the Iron Mask had Leonardo DiCaprio in duel roles. It takes place in I think France. DiCaprio is the terrible king Louis who sent his twin brother to prison and hid his identity with an iron mask so he could rule alone. When the three muskiteers break the twin out and reveal his identity after breaking off the mask, they go after King Louis to replace him with his good natured twin brother. The chances of them pulling it off don't look to high though. Can they make it? Don't miss this one, folks!!
