"Crazy Rich” people in a 2018 film (6)
I believe the answer is:
asians
'crazy rich people in a 2018 film' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for asians that I've seen before include "Eg, those from thirteen across" , "Natives of China, say" , "Natives of e.g. India" , "They come from countries such as India and Pakistan" , "Continentals" .)
