Film aficionados have long turned to the Walker for previews of new films before their broad release. And many—from recently screened works by Lars von Trier (Manderlay), Ang Lee (Brokeback Mountain), and Deepa Mehta (Water)—earned critical or popular acclaim. This ongoing series offers a first look at three compelling, incisive films that are shaping the art form. Screenings are $8 ($6 Walker members) and presented in the Cinema.
