In "Your Sister's Sister," set against the damp foliage of the Pacific Northwest, "Humpday" star Mark Duplass plays Jack, still reeling from his brother's death a year earlier. His close friend Iris (Emily Blunt), who happens to also be the ex of Jack's brother, ships him off to her family's remote vacation home so he can be alone to get himself back together.
Jack unexpectedly finds Iris' sister Hannah (Rosemarie DeWitt) there for similar purposes, and the two quickly get to know each other over an evening of tequila. When Iris arrives unannounced the next morning, it sets off a chain reaction of revelations and shifting dynamics.

2012 Guide Analysis: "Indie comedy darling Lynn Shelton's fourth film, her first since the critical and awards success for her 2009 mumblecore comedy "Humpday", kicked off its run on the film festival circuit in Toronto last year to quite good reviews. Critics called it a stronger and more polished affair than 'Humpday', but some stated that in spite of its natural performances and interesting exploration of human behavior, it over reaches in its final act.
The story has a guy named Jack (Mark Duplass) getting to spend a week alone at the family island getaway of his best friend Iris (Emily Blunt) so he can reflect on his life and get over the rut he's been in since his brother's death the year before. When he arrives there's a complication - Iris' older sister Hannah (Rosemarie DeWitt) is there and is getting over the breakup of a seven year relationship she was in with a girlfriend. Drinking leads to talking which leads to a quick roll in the hay and when Iris shows up it leads to the eventual reveal of a secret of Hannah's.
Rachel Weisz was originally cast as Hannah but a delay on this and filming commitments to "The Deep Blue Sea" got in the way, leading to DeWitt taking over. With each new effort Shelton's films have displayed increasing commercial appeal, a trend that will likely continue here."
