Matthew Williamson's 15th anniversary film 'XV' stars Sienna Milller, Poppy Delevingne and Andrea Riseborough. Directed by Tell No One, the film was shot at the imposing 17th century country house, Aynhoe Park in Oxfordshire and features eight ballerinas from the Royal Ballet, choreographed by the acclaimed Wayne McGregor, founder of the Random Dance company. With original script by Mark Whelan, the collaborative film makers Luke White and Remi Weekes created the mini movie as a snapshot into the imagination of a 15 year old Williamson, dreaming up his very own fashion fantasy with a very down-to-earth twist at the end.
