Actress Keira Knightley flashes a quick pose on her way into SoHo's Balthasar restaurant following the "Special Screening" of "Atonement," directed by Joe Wright (the U.S. premiere takes place next week in L.A. at the Academy theater.) Knightley along with co-star James McAvoy won praise among attendees for their performances in the film. Attendees also praised the swank after-party complete with champagne, and a huge spread of food and good times. The party went on for several hours and included actors Jason Lewis, Andrew McCarthy, Masi Oka, Eva Amurri and Griffen Dunne as well as director Mira Nair and more. When introducing the film, Wright looked out and said, "what a classy crowd."
