The first full-length trailer for Crazy Rich Asians is here, and it doesn鈥檛 disappoint. Over the course of two-and-a-half minutes, we see Rachel (Constance Wu) accompany Nick (Henry Golding) to visit his family and friends in Singapore, and plenty of drama ensues. But fans of Kevin Kwan鈥檚 trilogy will notice that there are some big differences between the Crazy Rich Asians trailer and the book. (Some spoilers ahead.)

The biggest change in the trailer is that in the movie version of the story, Nick鈥檚 family is well-known in Singapore. When Rachel visits her friend Goh Peik Lin (Awkwafina), Peik Lin鈥檚 father, Goh Wye Mun (Ken Jeong), immediately recognizes Nick鈥檚 name. Wye Mun informs Rachel that Nick鈥檚 family includes 鈥渢he biggest developers in all of Singapore.鈥 But in the book, that interaction is just the opposite. Rachel meets the Gohs before meeting Nick鈥檚 relatives, and none of Peik Lin鈥檚 family members have a clue who 鈥淣ick Young鈥 is.

In the novel version, Nick鈥檚 extended family is extremely dedicated to keeping their wealth under wraps. They make sure that stories about them never end up in local newspapers. And Nick鈥檚 grandmother鈥檚 mansion, Tyersall Park, is so secluded that Peik Lin鈥檚 family doesn鈥檛 even know the property exists.

It鈥檚 an understandable Hollywood change, though it will be interesting to see how it plays out if all three films are made. The family鈥檚 desire for privacy comes into play, in particular, in the third book, Rich People Problems, with Nick鈥檚 cousin Astrid (Gemma Chan). Still, this is only the first trailer, and it doesn鈥檛 show Nick鈥檚 grandmother yet.

The other big departure from the book appears to be Rachel鈥檚 relationship with Nick鈥檚 mother, Eleanor (Michelle Yeoh). In the novel, Eleanor is sneaky in her attempts to break up Nick and Rachel. She goes as far as to hire a private investigator to dig into Rachel鈥檚 family鈥檚 past, a detail that will probably still make it into the movie. But she and Rachel don鈥檛 outwardly snap at each other, at least not when they first meet, the way they do in the trailer.

Having Rachel and Eleanor at odds from the beginning could also alter Rachel鈥檚 storyline with Nick. Toward the end of the book, the leading couple briefly breaks up after Eleanor reveals what her investigator finds. But if Rachel and Nick鈥檚 mom have been disagreeing the whole time, she might stick by Nick鈥檚 side. Again, though, Rachel and Eleanor鈥檚 dynamic could change once Nick鈥檚 grandmother, Su Yi, comes into the picture. Su Yi, like Eleanor, doesn鈥檛 approve of Rachel, though she鈥檇 never casually tell her as much during dinner.

Overall, the differences might not be as significant as they seem from the trailer. Kevin Kwan is an executive producer on the movie, so he likely had a say in any major changes. And for fans of the trilogy, just the fact that the movie will be released in four months is cause for celebration.
