Daisy Ridley aka Rey of “Star Wars” fame is a revelation as the down-in-the-dumps lead character in “Sometimes I Think About Dying,” a slow-paced, slow-to-start, working-class drama from director and co-writer Rachel Lambert (“I Can Feel You Walking”). I hesitate to dub Lambert a mumblecore wunderkind since mumblecore is so over. But “Sometimes I Think About Death” has unmistakable mumblecore roots.

Ridley is Fran Larsen, a make-up-free singleton in Astoria, Oregon, who lives beside the mouth of the Columbia River surrounded by a lot of the world’s beauty: sky, fog-shrouded mountains, beaches full of driftwood, boats bobbing in a harbor, misty forests and water, water, everywhere. But none of it interests Fran, except when she imagines herself dead in one of these environments. Fran walks to work in an office of some sort, where she does not have much contact with her co-workers. After work, she pours herself a quick glass of wine and microwaves some breaded disc, which she garnishes with a topping of cottage cheese. Delicieuse, non?

We don’t know any more about Fran. We suspect something terrible has happened to her. She keeps everyone at arm’s length. We imagine that she’s trying to avoid being hurt. Fran prefers to be alone working on one of her puzzles. Of course, she’s the film’s biggest puzzle.

Back at work, retiring coworker Carol (a sublime Marcia DeBonis) tells everyone, Fran included, over cake that she is not going to cry and that she and her husband are going on that long deferred cruise. In her place is new guy Robert (Canadian actor and comedian Dave Merheje), who must order his office supplies through Fran, the administrative assistant. The office boss is the affable and effervescent, but also business-like Isobel (Megan Stalter, “Hacks”).

Robert declares himself a movie lover. Fran unexpectedly asks him if he’s been to the Columbian, one of Astoria’s movie theaters. He invites her to take in a film with him there. When asked what she thinks afterward (we don’t know what they’ve seen), Fran says she hated it. Although she’s come a bit out of her shell (boiled crabs will later serve as an unlikely, but tasty metaphor for Fran), Fran remains a mystery. In a discussion of what cheeses they like, Fran tells Robert that cottage cheese is not a cheese. “It’s a curd.” It rains in Astoria half the time. But Fran is a rebel. She doesn’t have an umbrella.

“Sometimes I Think About Dying,” which was co-written by Stefanie Abel Horowitz, Kevin Armento and Katy Wright-Mead, who all collaborated on the 2019 short version, is like a rom-com directed by David Lynch. I half expected to run into that crazed homeless guy from “Mulholland Drive” (2001). Tired of Robert’s probing questions, Fran tells him he’s “exhausting.” No wonder he’s had two failed marriages, she adds. “Please, go,” is his angry response. Fran spends the weekend sleeping on her floor. We continue to admire the 4-mile cantilever Astoria-Megler Bridge that opened in 1966, spanning Astoria and Point Ellice, Washington.

Why can’t Fran connect with such grace and brilliance? At a bakery, Fran runs into Carol. Why isn’t she cruising the world? Lambert and executive producer Ridley give DeBonis the film’s big, tear-jerking monologue, and she is a wonder. Over the final credits, we hear “With a Smile and a Song” from Disney’s “Snow White and the Seven Dwarfs” (1937) and the David Lynch and Angelo Badalamenti tune “Mysteries of Love” from Lynch’s 1986 classic “Blue Velvet.” Yes, Fran has been in a near-death slumber. If Robert is a flawed Prince and Fran is a depressed Snow White, who is the Evil Queen?
