The 55th San Francisco International Film Festival announced the complete schedule of films and events for the festival running April 19 – May 3, 2012, at Sundance Kabuki Cinemas, SF Film Society Cinema, the Castro Theatre and SFMOMA in San Francisco and the Pacific Film Archive in Berkeley.

The Centerpiece screening will be Lynn Shelton’s relationship comedy Your Sister’s Sister, starring Emily Blunt, Mark Duplass and Rosemarie DeWitt.

Still grief-stricken a year after his brother’s death, Jack (Mark Duplass) travels to a remote cabin on Puget Sound at the suggestion of his best friend, Iris (Emily Blunt), who thinks that he’ll benefit from the isolation. He arrives to find Iris’s sister, Hannah (Rosemarie DeWitt), recovering from a bad breakup, and they quickly bond over their shared misery. When Iris turns up to surprise Jack, she notes a new connection between him and her sister. What begins as a happy reunion soon deteriorates into a fractious encounter, the trio caroming off one another amid misunderstandings, betrayals and secret affections. Improvising much of the dialogue, the three actors are terrific, imbuing their complex, sometimes maddening characters with genuine heart. Shelton and her cast develop an idea initially conceived by Duplass into a funny, truthful story about sibling bonds, friendship, love and miscommunication.

The festival will close with Ramona Diaz’s (Spirits Rising, SFIFF 1996) Don’t Stop Believin’: Everyman’s Journey (USA 2012). Described as ‘Diaz follows the iconic, quintessentially American rock band Journey and new lead vocalist Arnel Pineda on their 2008 Revelation tour of the U.S. and Pineda’s homecoming in Manila.‘

The 2012 Kanbar Award for excellence in screenwriting will go to David Webb Peoples, who will be honored with an onstage tribute and a screening of his ‘acclaimed neo-Western’ film Unforgiven.
