Crazy Rich Asians star Henry Golding says that the movie's highly-anticipated sequel is taking longer than expected as director Jon M. Chu is ''trying to crack the script''.

The 33-year-old actor, who played the role of Nick Young in the hit rom-com admits the process of transferring the film from Kevin Kwan's novels to the big screen is challenging.

Speaking to Digital Spy, Golding said: ''They've got the two books that Kevin Kwan wrote still to come and they're trying to find an angle to convert those from page to script to film.

''It's a very complicated process because, visually, sometimes a novel doesn't make as much sense as it would on the screen in a direct adaptation. So you have to really change it up to make it interesting."

''The other issue is that we've got the first one to compete with, everybody has a very high expectation. It's not going to be as easy as the first one. It's still a work in progress, for sure.''

Golding , who has since starred in Last, Christmas, A Simple Favour and The Gentlemen, admits he "really" wants to "find my groove" and "not to be kind of pigeonholed".

''We've tried to cover the gambit, and to really find my groove - and also not to be kind of pigeonholed. That's the concern when you're in a big, breakout rom-com. Are you going to be that guy, Prince Charming, for the entire time?

''So I think I identified pretty early on that I wanted to create a block of work with a range. And I think that helped with the choices for sure.''
