D'Argtagnan's horse and the King's dogs were made by Jim Henson's Creature Shop in London
Milady de Winter's wigs were made higher and more beautifully styled than they were during normal performances, specifically for filming.
Queen Anna's dress in the hunt scene is made from the tips of hundreds of real peacock feathers sewn together.
The "Men" number performed by Milady de Winter was staged as a tribute to "The Cell Block Tango" in the movie "Chicago" which is performed by Velma Kelly. Pia Douwes, who plays Milady de Winter, played Velma Kelly in the stage version of "Chicago" in The Netherlands, London and on Broadway.
Costumes for the ball to celebrate the King's birthday were the most expensive in the show. The sleeves of the women's costumes each took 2 weeks to make with a team of 10 people working on them.
The "Fight" number at the end of the first half is a tribute to "One Day More" from "Les Miserables".
The story is set in 17th century France, although the costumes were designed to convey the flavor of the characters rather than being true to the period. As such, Milady de Winter wears dresses made from leather and PVC; the Cardinal wears red leather war clothing and Constance dresses like modern woman. The overall effect is that the story appears to take place either in the future or in a parallel universe.
Milady de Winter's brand is made of latex and glued onto Pia Douwes' arm and shaded to look more like a burn.
The rain in the scene in which the boat crosses the English channel was later added digitally.
The staging of "Not Made Of Stone" is a tribute to "Goodbye My Life" in the movie "All That Jazz".
