LOS ANGELES — It’s been 25 years since a major Hollywood studio released an English-language film with a primarily Asian cast. The last was Wayne Wang’s adaptation of the generational tear-jerker “The Joy Luck Club,” which was released in 1993.

But that dry spell is about to end with the release of the opulent romantic comedy “Crazy Rich Asians” on Wednesday. The film is based on Kevin Kwan’s best-selling book about a Chinese-American woman who gets a culture shock when she meets her boyfriend’s wealthy family in Singapore.

Veteran producer Nina Jacobson said that when she and her Color Force partner Brad Simpson (“The Hunger Games”) read Kwan’s manuscript, they knew it had to be a movie.

“We just tore through it,” Jacobson said. “It was so specific that it became really universal: Anybody who has ever faced in-laws who felt that they were not worthy of their beloved.”

They knew that the film would likely never survive the studio development process, however, and decided to have a vision, a script and a budget to sell as a package before going to the marketplace.

“Hollywood has done a bit of a disservice by not taking us into these worlds,” Simpson said. “There is a hunger for not just token representation but to really dive into the world of different ethnicities and races.”

Meanwhile, Jon M. Chu, who would eventually sign on to direct “Crazy Rich Asians,” had already been hearing about this new book from family members. His last name is the same as that of the main character, Rachel Chu, and they’re both from Cupertino. There’s even a reference to his family in Kwan’s book, but ultimately the book spoke to the uniqueness of the Asian-American experience.

“I think a lot of Asian-Americans go through the same journey ... I relate to having that dual cultural identity of being full-on all-American, all-California boy, but having a Chinese side to me,” Chu said. “I remember going to Asia for the first time and there’s a very specific emotion that you feel that’s like, ‘Oh, this feels like home but it’s not my home and these people don’t see me as being part of this.’ Then when you’re home you start to notice people may not see you as part of that either.”
