of Stormhold. The Briton's Arms tea house became the Slaughtered Prince public house. The owners were so enthralled with the new look, including a spectacular mural and new thatching, that they appealed to the local council and English Heritage to keep it, but their request was refused. Filming also took place in Wales, at the Brecon Beacons National Park. The design of the witches' lair was inspired by the Hall of Mirrors in the Palace of Versailles in France, but with black instead of white and silver instead of gold. Filming was finished by 13 July 2006. Visual effects The film required 830 visual effects (VFX) shots which were supervised by Peter Chiang and produced by Tim Field. Double Negative supervised 350 shots, and other work was shared out among six other companies including LipSync Post, Cinesite, The Senate, Baseblack, Machine and Rushes. Mattes & Miniatures provided miniatures. The pirate skyship set was shot against a 360 degree greenscreen and required fully CG backgrounds and digital extending the size and the bow of the ship. Some distance shots of ship were entirely CG. Yvaine required a star glow effect for more than eighty shots. Two of the witches required a signature magical effect, Lamia had a green fire effect created using a combination of particle animation and joint-driven soft body ribbons, and Sal had a black smoke effect, created by turning animated geometry into a target-driven fluid simulation. The age transformation of Lamia was achieved using composite of multiple motion control plates, including a pass in the full prosthetic makeup, the transformed youthful Lamia, and a pass where the hair was pulled through a dummy head, played in reverse to give the appearance of hair growing, composited and blended with a procedural glow effect. Twenty feet of The Wall was built on location as a practical effect and extended into the distance using digital painting. VFX were completed by February 2007. Music The film score was composed by Ilan Eshkeri, who previously worked with Vaughn on Layer Cake. Eshkeri was given the script before production began and wrote the first pieces of music inspired by the illustrations of Charles Vess from the graphic novel. Eshkeri was also on set during some of the filming. The score was released by Decca Records on 11 September 2007. Eshkeri won the award for Best New Composer of 2007 from the International Film Music
