Warner Bros. Pictures’ “Aquaman” is already doing swimmingly in theaters. The new DC installment opened in China this weekend, breaking the record for DC debuts in the country. Estimates are that “Aquaman” grossed over $94M at the box office this week, a great start for what is sure to be one of Warner Bros. Pictures‘ top films of 2018.

China was the first market that Aquamam swam into this year, after the China Film Group allowed the film to be distributed within the country. “Aquaman” stars Jason Momoa in the titular role and the film was directed by James Wan. While Chinese audiences are still drying off from the undersea adventure, North America will have to wait until December 21st to see the film in theaters.

“Aquaman” might be making waves overseas but he will have some stiff competition at the box office on his domestic opening weekend. The King of Atlantis will have to battle Disney’s “Mary Poppins Returns” in theaters that same weekend, but the DC superhero is catching a break since Disney is releasing the film on Wednesday, December 19th. Disney gave the long awaited sequel a Wednesday debut in order to beat the expected weekend rush and to allow the film to open at number-one on its debut night without competition.

Even with “Mary Poppins Returns” opening three-days before “Aquaman,” Warner Bros. Pictures still has to compete with Paramount Pictures’ new Transformers’ spinoff “Bumblebee,” which is marketed towards many of the same demographics. That film was directed by Travis Knight and features Hailee Steinfeld and John Cena. Also opening that weekend is “Second Act,” a romantic-comedy that stars Jennifer Lopez, Vanessa Hudgens, Treat Williams, Milo Ventimiglia, and Charlyne Yi, as well as Robert Zemeckis’ “Welcome to Marwen” with Steve Carell.

When compared to his fellow DC superheroes, “Aquaman” will want to top “Batman vs. Superman” which had a $166M opening back in 2016. If Aquaman wants to go the distance, he will have to do better than Wonder Woman’s $412M domestic gross in theaters.
