Warner Bros. has unleashed the seven seas onto the Middle Kingdom.

James Wan’s Aquaman made a giant splash in its China debut, grossing $93.6 million to land the top showing ever for a DC comic book adaptation two weeks ahead of its North American debut. The film marks the biggest opening ever in China for any Warner Bros. title, besting Steven Spielberg’s Ready Player One by 66 percent.

Aquaman also delivered the biggest industry opening for the month of December, commanding 85 percent of market share.

Among Warner Bros./DC movies, it launched 92 percent ahead of Justice League, 78 percent ahead of Batman v Superman: Dawn of Justice, and it’s already passed the entire lifetime haul of Wonder Woman.

Warner Bros. decided to unveil Aquaman first in China, followed by additional foreign markets in the upcoming week, in order to get a jump on a incredibly competitive pack of year-end holiday films, including Disney’s Mary Poppins Returns and the Transformers spinoff Bumblebee.
