BoxOfficeMojo reports: The Hobbit opened to $18.1 million in China this weekend. According to Warner Bros., that’s the fourth-biggest three-day start ever for a U.S. movie. That brings the movie’s foreign total to $679.6 million (12th all-time); it’s also now less than $20 million away from passing $1 billion worldwide, which it should be able to do if China keeps it in theaters for a full two weeks.
