“Crazy Rich Asians” keeps getting richer, topping the North American box office for a third week in a row and taking in more than double the weekend earnings of the second-highest-grossing film.

Continuing to signal the market’s desire for more diverse voices in big-budget movies, “Crazy Rich Asians” (Warner Bros.), led by Asian stars, sold about $22.2 million in tickets from Friday to Sunday. The sales are the latest demonstration of the film’s staying power, representing a decrease in earnings of only around 10 percent from the previous weekend and perhaps reaffirming Warner’s plans to move forward with a sequel.

“Crazy Rich Asians,” adapted from a 2013 novel by Kevin Kwan, has now swept up nearly $111 million in North America, according to comScore, which compiles box-office data.

Also for the third weekend in a row, “The Meg” (Warner Bros.) came in second. The blockbuster-by-design aquatic thriller with Jason Statham and a giant shark-thing sold about $10.5 million in tickets, bringing its domestic total up to around $120.5 million. While the film exceeded box-office expectations during its opening weekend, it has since consistently trailed “Crazy Rich Asians” — though not quite enough to lose its lead of about $10 million in cumulative North American earnings.
