While researching her role for a new film Past Lives, Greta Lee watched a South Korean reality show in which a celebrity is reunited with a childhood sweetheart. Being confronted by your first love is, unsurprisingly, a physical experience. “It’s initial shock, terror, a look of death, then ecstasy, joy and a desperate, deep sadness, all within a matter of seconds,” says the 40-year-old Korean-American actor on a video call from Los Angeles, where she lives with her husband, the writer Russ Armstrong, and their two sons.

It was a specific feeling she needed to tap into for the romantic drama from writer-director Celine Song, which is out now in cinemas and was released earlier this summer in the United States to considerable critical acclaim. The film charts the story of two friends from South Korea: Nora, played by Lee, and Hae Sung, played by Teo Yoo, who were separated when Nora’s family emigrated to Canada. A couple of decades (and relationships) later, the pair reconnect for an intense week in New York.

Before Nora and Hae Sung’s reunion was filmed, Song asked the actors not to interact. “Admittedly, at the time I felt like, ‘Oh, this is kind of hokey and manufactured,’ but I’m glad we went along with the experiment, because it really helped me hone in on the biology of longing and what it does to your body,” says Lee. Yoo and John Magaro, who plays Nora’s husband Arthur, actually met for the first time on screen; for months, Lee had acted as a “conduit” between the two, a distance that Song encouraged. “She’s supremely manipulative,” Lee jokes.

Taking on Nora, a nuanced romantic lead, “felt really, really radical at the time — and very nerve-racking”, says Lee. While she was starting out as an actor, doing theatre in New York, the roles available for Asian-Americans were scarce and, as Lee points out, she wasn’t cut out for stereotypes: “I was not very good at playing a lab technician or a doctor.” Later, however, she proved very cut out for scene-stealing turns in Girls, as the clueless and cut-throat gallerist Soojin, and more recently as Maxine in Netflix’s time-bending hit Russian Doll and Stella in The Morning Show, which is about to start its third season. In 2025, she is set to star alongside Jared Leto in the third instalment of Tron.

Central to Past Lives, says Lee, is the Korean concept of in-yun. Not precisely translatable, it refers to the time-spanning connections between people: if you meet in this life, you encountered each other in a past life. “Now that I’ve done the movie, I can’t not see in-yun everywhere,” Lee says, with the air of a recent convert to a niche religion. “You and I have in-yun now,” she says, pointing to me. “You can have in-yun with a chair,” she adds, pointing at her chair. Wherever you stand on the idea — as Nora says in the film, in-yun is “just something Korean people say to seduce someone” — it’s an effective way to raise the romantic stakes; both balm and delusion. “It’s really a coping mechanism, isn’t it?” says Lee, cheerily. “We’re all just trying to make sense of the injustice that we only get to live once.” ○

‘Past Lives’ is in cinemas now.
