Stephanie Hsu is really busy — the “Everything Everywhere All at Once” Oscar nominee has been commuting from California to Australia for the past few weeks while filming “The Fall Guy” with Ryan Gosling and attending various events and ceremonies to promote “Everything Everywhere,” directed by Daniel Kwan and Daniel Scheinert, which earned 11 Academy Award nominations. She beams with pride when discussing this moment in her life. The daughter of a Chinese immigrant who was a single mother, Hsu has been talking with her family and friends about the road that’s led her to this moment — including her best friend Alan, who told her she did it without having to be “born into this industry,” or a family friend emailing her mother to recall the time she brought a young Hsu to the friend’s house intending to convince her to study business. “Aren’t you glad she didn’t?” the friend wrote.
