Fans take close look at reality of film production

In the 2014 film Beauty and the Beast, the heroine Belle walks onto the balcony of a palace and takes a look below. The houses, streets and citizens form a grand landscape of her fictional kingdom. There is a surprised look in her eyes.

But if you thought the actress playing Belle really saw the scenes portrayed, you are mistaken. What she saw during the shooting was a huge green screen, but the director looking at the camera view would see the complete scene with the actress in it.

Experts showcased this cutting-edge technology to visitors at the opening of the 2015 China 3-D Technology & Creation Expo.
