“Crazy Rich Asians” topped the North American box office for a second weekend in a row, as a new Melissa McCarthy vehicle failed to live up to already-meager expectations.

Powered in part by pent-up demand for a studio film led by Asian stars, “Crazy Rich Asians” (Warner Bros.) sold about $25 million in tickets between Friday and Sunday — a decrease of only 6 percent compared to its opening weekend. That kind of audience “hold” is extremely rare and indicates exceptional word-of-mouth sales; most films drop between 30 percent and 60 percent from weekend to weekend.

“Crazy Rich Asians” has now collected about $76.8 million in North America, according to comScore, which compiles box office data. Warner has already started to develop a sequel to the film, which has been heralded as a watershed moment for representation on the big screen. A romantic comedy, “Crazy Rich Asians” is the first Hollywood movie with an all-Asian cast and a contemporary story since “The Joy Luck Club” in 1993.

So far, ticket sales for “Crazy Rich Asians” have been less impressive overseas, where the film has only taken in about $7.1 million in a handful of smaller territories. Large countries like Britain will follow in the weeks ahead, although it is unclear whether China, the world’s second-largest film market behind North America, will grant Warner’s request to import the movie. China operates a quota system for foreign films.
