You shouldn’t judge a book by its cover, but sometimes, you can take one look at a book and know it’s going to be good. “Interior Chinatown” is that kind of book. A purposefully distressed red cover is simultaneously reminiscent of a red packet, a newspaper cover, and a playbill.At the center is a small Chinatown gate; the interior area of the gate frames are filled by what resembles a prison or a birdcage. Based on Charles Yu’s 2020 novel of the same name, Hulu’s Interior Chinatown is a layered, reality-bending tale that follows an actor named Willis Wu. He’s used to playing small, background roles — he calls them “Generic Asian Man” — on a police procedural called Black and White. But he dreams of working his way up to a bigger part, one he calls “Kung Fu Guy.”
