Your Sister's Sister (2011)
Director: Lynn Shelton
Some films are epic in scope and length, with a cast of hundreds or thousands, and with often a running time to match. Shelton's film is the complete opposite to that; three main actors, the entire film almost occurring in one setting, and the action predominantly made-up of conversations. The simplicity of the film belies the complexity of the situation between two sisters and a friend, as they try to hide important truths from each other.
Emily Blunt, Mark Duplass and Rosemarie DeWitt are all fantastic; this really is an actor's film. Parts of the script were improvised, and Shelton has clearly got the balance right in her direction. The result is natural performances that are funny, emotional and ultimately believable.
An intelligent film that proves the value of small budget films (and they don't come much smaller than this).
