This movie is loaded with stars, Ian McShane, Ursula Andress, Beau Bridges (in the duo role) and Lloyd Bridges, Alan Hale Jr., Cornel Wilde, Rex Harrison, Olivia de Havilland and Jose Ferrer. The costumes are scrumptious and the locale work all help this movie along. It's good to see the old 50s movie stars having one last swashbuckle! Bridges is miscast and nearly sinks the movie, and the directing is stiff, but everyone does a good turn in the old Man in the Iron Mask story. McShane seems to have fun as Fourquet.
The much-filmed Dumas tale has the Philippe, twin brother of the King of France, raised and protected by the Musketeers. Fourquet, acting for the King, has the twin arrested and hidden by the iron mask. He plans to use the twin as a decoy in public, and kill him with a bomb. Then when the King surprisingly survives the attempt, it's supposed to make everything believe he is invincible. Only the musketeer is Johnny-on-the-spot to foil the plot, save their ward and then pull the switch by stuffing Louis the King in the iron mask and place Philippe on the throne of France.
It's a good transfer. Just a shame the younger Bridges hurt the effort in the dual role and the directing could not have been stronger.
