Walker, Texas Ranger is an American action crime television series created by Leslie Greif and Paul Haggis. It was inspired by the film Lone Wolf McQuade, with both this series and that film starring Chuck Norris as a member of the Texas Ranger Division. The show aired on CBS in the spring of 1993, with the first season consisting of three pilot episodes. Eight full seasons followed with new episodes airing from September 25, 1993, to May 19, 2001, and reruns continuing on CBS until July 28, 2001. It has been broadcast in over 100 countries and has since spawned a 2005 made-for-television movie entitled Trial By Fire. The movie ended on a cliffhanger, which was never resolved. DVD sets of all seasons have been released (with the three pilots packaged with the first regular season). At various times since 1997, reruns of the show have aired, in syndication, on the USA Network and Action in Canada. Reruns are currently seen on CBS Action, WGN America, INSP and Grit, 10 Bold, being part of Network Ten in Australia and now also airing on Charge! (TV network) Broadcast Network.
