The Walker (2007)

The Walker is a 2007 drama film that was written and directed by Paul Schrader. It is a British-American independent production and was proclaimed to be the latest installment in Schrader's "night workers" series of films, starting with Taxi Driver in 1976, and then followed by American Gigolo in 1980 and Light Sleeper in 1992. Carter Page III (Harrelson), a middle-aged gay man in Washington, D. C., is a "walker", a single man who escorts other mens' wives to social events so the husbands do not have to. One of the women he escorts, Lynn Lockner (Scott Thomas), is the wife of a United States senator and is carrying on an affair with a lobbyist. When she finds the lobbyist murdered, she embroils Carter in an investigation that leads to the highest levels of the federal government.
