'Black Panther' now highest-grossing superhero film in North America

NEW YORK (AP) -- It took six weeks but "Black Panther" has finally been unseated as the top film at the box office. The monsters vs. robots science-fiction sequel "Pacific Rim: Uprising" has dethroned "Black Panther" with an estimated $28 million in weekend ticket sales.

According to studio estimates Sunday, "Black Panther" slid to second place with $16.7 million in its sixth week. The superhero sensation still marked the weekend with another box-office record. It's now the highest-grossing superhero film ever in North America, not accounting for inflation.

The Christian drama "I Can Only Imagine" came in third with $13.8 million in its second weekend. The animated sequel "Sherlock Gnomes" opened with $10.6 million. Wes Anderson's "Isle of Dogs" scored one of the year's best specialty releases with $1.6 million in 27 theaters.
