LOS ANGELES - It has been another crazy good weekend for rom-com "Crazy Rich Asians," which topped the box office for a third straight weekend amid a pretty good summer for North American theaters overall, industry watchers said Monday.

The Warner Bros. film, with its mostly Asian cast, took in an estimated $22.2 million for the Saturday-through-Monday period, dropping just 10 percent from the previous weekend, box office tracker Exhibitor Relations said.

The adaptation of Kevin Kwan's best-selling novel, starring Michelle Yeoh, Henry Golding and Constance Wu, follows an American economics professor as she meets her super-rich boyfriend's family in Singapore in a story about the clash of love, family and great wealth.

Warner Bros. meanwhile scored another hit with shark-thriller "The Meg," in the No. 2 spot again with takings of $10.5 million. Jason Statham stars as a rescue diver trying to save scientists trapped in a submarine being attacked by a huge, prehistoric shark.

In third spot was Tom Cruise adventure film "Mission Impossible - Fallout" from Paramount, which took in $7 million. Globally, the action blockbuster has earned $649 million, the best performance of any of the "MI" films to date.

Fourth went to MGM's new "Operation Finale," at $6 million. Oscar Isaac plays an Israeli Mossad agent who tracks Nazi war criminal Adolf Eichmann (Ben Kingsley) to the Buenos Aires suburb where he is living under a false name.

And in fifth was "Searching" from Sony, at $5.7 million. Written and directed by filmmaker Aneesh Chaganty, it tells the story of a Korean-American man's desperate effort to find his teenage daughter after she goes missing in California. It stars John Cho, Michelle La and Debra Messing. - AFP
