Gerwig is drawn to the “euphorically dreamlike” quality of Lewis’ writing. “It’s connected to the folklore and fairy stories of England, but it’s a combination of different traditions,” she says.“As a child, you accept the whole thing—that you’re in this land of Narnia, there’s fauns, and then Father Christmas shows up. It doesn’t even occur to you that it’s not schematic. I’m interested in embracing the paradox of the worlds that Lewis created, because that’s what’s so compelling about them.”
