Terrific news: Lynn Shelton's Your Sister's Sister—her first film since the beloved Humpday—has been announced as the opening night film for the 2012 Seattle International Film Festival. From the official press release:

Your Sister’s Sister, written and directed by Seattle’s Lynn Shelton and starring Emily Blunt, Rosemarie DeWitt and Mark Duplass, will be the centerpiece of SIFF’s 38th Opening Night Gala and Red Carpet Experience, which will offer an exclusive screening of the film before it hits theatres this summer through IFC’s Sundance Selects.

I saw Your Sister's Sister last autumn and really enjoyed it. Of course the acting's lovely (especially Rosemarie DeWitt, who you might know from Mad Men) and the whole thing's based around a sisterly relationship of a type I've never before seen on film. (That sounds salacious, but it's more of a humane and idiosyncratic thing.)

Congratulations, Lynn Shelton and SIFF!
