The Walker is a 2007 independent crime drama film written and directed by Paul Schrader and starring Woody Harrelson, Kristin Scott Thomas, Lauren Bacall, Ned Beatty, Lily Tomlin, Willem Dafoe, Moritz Bleibtreu and Mary Beth Hurt.

It is the fourth installment in Schrader's night workers series of films, starting with Taxi Driver in 1976, followed by American Gigolo in 1980 and Light Sleeper in 1992.

One of the women he escorts, Lynn Lockner, is married to a United States senator and is having an affair with a lobbyist.

Initially the film was to be a direct sequel to American Gigolo, with Julian Kaye (played by Richard Gere) as the lead character.

The Walker was released direct-to-DVD but played in an independent film theater for two weeks in Dorris, California.
