Jean Pierre Amiel is a Swiss actor and mime who provided choreography and mime coaching for The Dark Crystal, and also performed UrUtt, the Mystic weaver. Amiel has worked in television and film and has his own theater company, Theater du Corps Compagnie Amiel, that travels the world with various productions. He founded and built a theatrical center in the African Congo in 1992.
Amiel was cast in The Dark Crystal after Creative Supervisor Sherry Amott spotted him at the London Mime Festival. Amiel used his own contacts to cast many of the other roles for mimes, acrobats and dancers in the film. It was he who discovered one of his mime's talents for stiltwalking and solidified the idea for the Landstrider costume.
