The word “crazy” in the title Crazy Rich Asians is an adverb meaning extremely.

I would have guessed that usage began around the 1960s or so, but it turns out that it dates back to the late 19th century.

All of the cites given by the OED seem to relate to a mental state (crazy anxious etc) making me think that perhaps this usage began as specifically as an intensifier of mental states, but a bit of a look around Google Books tells me that there are plenty of early examples of crazy just meaning extremely in other cases.
