"Aquaman" is still the champ at the box office three weeks in, but the high-concept thriller "Escape Room" also drew some substantial crowds in its debut weekend.

Warner Bros. on Sunday said that "Aquaman" added an estimated $30.7 million from over 4,000 North American theaters. That brings its domestic grosses to nearly $260 million. The DC comics film starring Jason Momoa has had a tidal wave of successes internationally too.

Worldwide it has made $940.7 million, making it by far the highest grossing film in the modern DC Extended Universe slate.

Even with the slew of holiday releases, from blockbusters to awards darlings, Sony's PG-13 rated thriller "Escape Room" managed to sneak into second place in its first weekend in theaters generating an estimated $18 million in ticket sales — double its production budget.

Disney's "Mary Poppins Returns" landed in third place in its third weekend with $15.8 million. The nostalgic musical has earned $138.7 million domestically and is competing for four Golden Globe Awards Sunday evening. Globally, it's made $257.9 million.

The Dick Cheney biopic "Vice" fell only 25 percent in its second weekend, adding $5.8 million to take seventh place.
