Writer/director Lynn Shelton's independent romantic dramedy "Your Sister's Sister" has been picked up by IFC Films for distribution in North America and Latin America, according to Indiewire. They have slated the film for release sometime next summer.

"Your Sister's Sister" stars Mark Duplass as Jack, a man still mourning the death of his brother from over a year ago. When his brother's former girlfriend Iris (Emily Blunt) sends him off to recuperate at her father's cabin on Puget Sound, he discovers that her sister Hannah (Rosemarie DeWitt), also nursing a broken heart, has set up shop there as well. When the two wake up together the next morning after sharing a night of drunken passion, complications ensue when Iris makes a surprise visit.

Shelton's last film was the well-received "Humpday" from 2009, also starring Duplass. More recently, she directed an episode of "Mad Men" entitled "Hands & Knees".

Blunt's other film at TIFF, the Lasse Halstrom-directed "Salmon Fishing in the Yemen", was picked up by CBS Films earlier in the week.
