Chinese Box Office

Maoyan Weying, China’s biggest online movie ticketing platform, is planning a Hong Kong initial public offering that could raise about $1 billion, people with knowledge of the matter said.

Some Chinese theaters are shortchanging U.S. film studios whose movies are shown in the world’s most populous country, according to a person familiar with an audit conducted by the Motion Picture Assn. of America.

The World War II rescue tale “Dunkirk” dominated the box office in China last week, building on its international success.
