50 Years of SIFF

Hometown heroine Lynn Shelton’s fourth feature and follow-up to the acclaimed Humpday is an engaging, humor-infused relationship drama about how the sibling and romantic relationships of three people are redefined over the course of a weekend island getaway. The cast (Emily Blunt, Rosemarie DeWitt, Mark Duplass) excels under Shelton’s signature method of marrying improvisation and scripted dialog. BETH BARRETT CHOICE.

“What can I say about Lynn Shelton, and Your Sister’s Sister? Lynn had a command of the story like few directors did, and that understanding of where the story was going to go allowed her actors to live in it, to take their characters deeper, and to create new avenues into Lynn’s vision. Her love and care for everyone involved with the production comes through in every frame of this film: the relationships, the humor, the free range of emotional vulnerability that makes even the darkest moment somehow mean more, and feel a little lighter for having happened.”--Beth Barrett, SIFF Artistic Director

Hometown heroine Lynn Shelton’s fourth feature and follow-up to the acclaimed Humpday is an engaging, humor-infused relationship drama, shot entirely in the Northwest. A year after his brother’s death, Jack (Mark Duplass) is alternately emotionally wobbly and outright volatile. When he makes a scene at a memorial party, good friend Iris (Emily Blunt) arranges for Mark to take a solitary retreat at her father’s cabin on a Puget Sound island, theorizing this isolation will offer closure and spiritual relief. When he arrives at the cabin, however, he finds not solitude but Iris’ sister Hannah (Rosemarie DeWitt), herself nursing a wounded heart and a bottle of tequila. After several shots and some slurred commiseration, romantic complications unfurl, growing in complexity when Iris arrives at the cabin unannounced the next morning. Shelton’s maturation as a filmmaker is on full display here; the stellar cast excels under her signature method of marrying improvisation and scripted dialogue, resulting in a pitch-perfect comedy of errors. Though ripe for love-triangle trappings, Your Sister’s Sister offers an uncontrived navigation of romantic rivalry and sibling relationships, rendered with equal parts pathos, humor, and intelligence.
