As you can see from the way Wu's clutching to that portable fan, filming Crazy Rich Asians was hot — in a not-so-hot way.
"The problem was that we shot this film in Malaysia, and the humidity was at 85 percent," Merker said. "It was too hot, and then the hair would straighten out pretty fast, even if you had the best curl and used lots of hairspray. It was nice when we could do [updos], but if there was a day where everyone had long straight or long curly hair, it was a disaster."
