Trailer for Ursula Meier's Knockout Silver Bear Winner 'Sister' with Lea Seydoux & Kacey Mottet Klein

The trailer for Ursula Meier's "Sister" had landed. The film is a knockout, both excitingly fresh and powerfully moving. It won the Silver Bear at Berlin and features Lea Seydoux's best-yet performance and a star-making turn from Kacey Mottet Klein as a professional 12-year old ski-resort thief. Fans of the Dardenne brothers' work, especially last year's "The Kid with the Bike," will likely fall for this one as well.

"Sister" is Meier's second feature. Her first, "Home," was nominated for three Cesars and participated in Cannes' L'Atelier du Festival (works in progress program) in 2006.

Check out the new trailer and our interview with Meier and star Kacey Mottet Klein from the Los Angeles Swiss Consulate's reception for the film during the LA Film Fest below. Meier discusses her career and the no-women-directors-in-competition-at-Cannes controversy. You can also check out our exclusive clip from "Sister" and our complete report LAFF.

"Sister" opens in New York October 5 and Los Angeles October 12.

The Synopsis: Simon (Kacey Mottet Klein) lives with his older sister (Lea Seydoux) in a housing complex below a luxury Swiss ski resort. With his sister drifting in and out of jobs and relationships, twelve-year-old Simon takes on the responsibility of providing for the two of them. Everyday, he takes the lift up to the opulent ski world above, stealing equipment from rich tourists to resell to the local kids down in the valley. He is able to keep their little family afloat with his small-time hustles and his sister is thankful for the money he brings in. But when Simon partners with a crooked British seasonal worker, he begins to lose his boundaries, affecting his relationship with his sister and plummeting him into dangerous territory.
