Synopsis

In 17th-century France, the aging Musketeers discover that cruel King Louis XIV has a secret twin brother imprisoned behind an iron mask.

Their daring conspiracy forces them to confront divided loyalties, old friendships, and the cost of political idealism.

Factoids & Trivia

• The film is loosely adapted from the final section of Alexandre Dumas' D'Artagnan saga, commonly published as *The Vicomte de Bragelonne: Ten Years Later*. Its version of the twin-brother mystery takes considerable liberties with Dumas' story.

• Two different films titled *The Man in the Iron Mask* were released in 1998. The other was a much smaller production that also drew from Dumas' material, creating an unusual same-year title clash.

• Principal photography took place in France, including the Royal Chateau of Fontainebleau, Chateau de Vaux-le-Vicomte, Chateau de Pierrefonds, and locations in Paris.

• Chateau de Vaux-le-Vicomte serves as the king's principal residence in the film. This choice also reflects the story's period, when Versailles had not yet become Louis XIV's established seat of power.

• Leonardo DiCaprio plays both Louis XIV and Philippe, making the contrast between the tyrannical king and his more compassionate twin central to the film's star performance.

• The production had an estimated budget of $35 million and earned approximately $183 million worldwide, turning the period adventure into a substantial commercial success.

• The film's score by Nick Glennie-Smith later found a life beyond the movie, with selections used as musical accompaniment for competitive figure-skating routines.

• Aramis' line, "I am a genius, not an engineer," contains a wordplay reference that is more apparent in the original French wording.
