Filming "The Grand Master" in Liaoyang War Museum Old Building and it's hard to see any of the stars as the crew has not allowed others to stay in the hotels. The arrival of Wong Kar-wai, Tony Leung, Zhang Ziyi, and martial arts choreographer Yuen Woo-ping caused quite a stir with many people arriving to see the stars. The crew have worked hard to secure areas of the museum, with "under constructuction" and "closed" signs hung outside the doors. "The Grand Master" crew have signed confidentiality agreements to prevent leaks, with the museum also signing an agreement.They filmed indoors until the early hours, with Wong Kar-wai wearing sunglasses at the midnight shooting. Security is extremely tight and impossible to see the cast. Zhang Ziyi was spotted and described as being verythin and pale and Tony Leung also lost weight.
