The 'Crazy Rich Asians' actor has signed on to the new movie alongside Jessica Rothe and the pair will play real-life couple Solomon Chau and his wife Jenn Carter as they plan their wedding after receiving devastating news.

The couple were in the middle of wedding preparations in 2014 when Chau was diagnosed with liver cancer. They moved up the date of their wedding and set up a GoFundMe account and were married for four months before he passed away.

'My Friend Dahmer' director Marc Meyers will helm the movie, based on a script by Todd Rosenberg.

Todd Garner and Sean Robins will produce the movie for Broken Road Productions, while Universal's Sara Scott and Lexi Barta will also produce.

Harry appeared briefly in 'Crazy Rich Asians' as Charlie Wu, Astrid Leong's ex and although his part was dramatically cut due to time constraints, he is expected to feature heavily in the sequel.

Director Jon M Chu said: "What we put in the movie was great -- they actually dance together -- and it was so awesome, and Harry's so charming and so lovable. But the problem was, it made Astrid feel like she was leaving [her husband] Michael for Charlie, and we didn't have enough room to expand on the idea. We just had to stay focused. Ultimately it's about her independence, so that scene was in there all the way until the very end. When we took it out, Astrid's journey became stronger. It was about her, not about her finding love."
