Sci-fi thriller "Mercy" starring Chris Pratt debuted atop the North American box office with $11 million in ticket sales, ending the five-week reign of "Avatar: Fire and Ash," industry estimates showed Sunday.
Pratt plays a man on trial for murdering his wife in the Amazon MGM Studios film, with his fate in the hands of an artificial intelligence judge.
The brutal winter storm hitting a large swath of the United States cut into the weekend totals, according to David A. Gross of Franchise Entertainment Research.
"Considering the extreme weather that's closing theaters across two-thirds of the U.S. and keeping people home, it's a very good opening," Gross said of "Mercy."
"The final numbers may be lower on Monday after we see the effects of the cold and snow."
"Avatar: Fire and Ash," the third installment in James Cameron's blockbuster fantasy series, came in second in the United States and Canada with another $7 million, Exhibitor Relations said.
That puts its domestic box office haul at $378.5 million, with an additional $1 billion overseas, according to Box Office Mojo.
Disney's Oscar-nominated animated film "Zootopia 2" churned along, remaining in third place at $5.7 million and crossing the $400 million mark in the U.S. and Canada.
In fourth place at $4.2 million was Lionsgate's "The Housemaid," an adaptation of Freida McFadden's best-selling novel about a young woman who is hired by a wealthy couple with dark secrets.
In fifth place was "28 Years Later: The Bone Temple," the fourth installment in the zombie horror series, at $3.6 million.
