"The Walker", starring Woody Harrelson, directed by Paul Schrader, is an exquisite study of Washington Society. Harrelson plays a gay escort – a "walker" – whose world crumbles when he becomes an unwitting witness to a brutal murder. The bitchy shallowness of Washington's high society is captured by a distinguished cast which includes Lauren Bacall and Kristin Scott-Thomas. It has been widely praised as Schrader's finest film for years.
