Seth Rogen and Michelle Williams are a couple whose marriage is threatened by her passion for the proverbial neighbor in Sarah Polley's drama, which costars Sarah Silverman. "I became obsessed with the idea of our feeling of emptiness, in the Buddhist sense, and that the most obvious way of filling it is with relationships," says Polley, who also wrote the film. "I think we aren't culturally comfortable not filling it, so we decide it's about our relationship. I wanted to make a movie that was about that emptiness, but also about desire, and our desire to fill it." (June 29)
