Director Jon M. Chu revealed that Michelle Yeoh was dissatisfied with the mock-up ring that her character, Eleanor, was going to wear. She showed him a ring from her personal collection and this eventually became the emerald and diamond ring Eleanor wears in the movie.
A sequel is confirmed and it is based on the second book of the trilogy, "China Rich Girlfriend."
As of October 2018, the film had grossed over $235 million worldwide, making it the highest-grossing romantic comedy in a decade.
Netflix wanted to produce the film and offered a much bigger budget, but Kevin Kwan deliberately turned down the offer in favor of a modest $30-million budget from Warner Bros. This was done to send a message that Asian-American studio movies are commercially viable.
