Their newest performance piece entitled "The Mexican Giant, the Dog Xolo, and the Little Indian Girl" was performed in Guadalajara last November and in Nantes last month.
The way they operate these giant marionettes is astounding. It obviously takes such brute force and muscle but the result is magnificently subtle and gentle. The little girl moves her eyes around in a completely human, sensitive way, taking in the small world around her. Take a look at the troupe in action here with their piece "The Sultan's Elephant."
And here is a French language feature about the piece "The Diver and the Little Girl."
Royal de Luxe have no website but Les Machines de l'Ile, the company that designs and fabricates the marionettes has a site... they also have an interactive museum/ budding theme park in Nantes that looks fantastic!
