The show was initially developed by executive producer Allison Moore and supervising producer J. Michael Straczynski when the series was still being produced by Cannon Television. While Straczynski had to depart to get his new series "Babylon 5" on the air, executive producer David Moessinger remained to finish developing the series. The show is centered on Sergeant Cordell Walker (Norris), a Dallas–Fort Worth–based member of the Texas Rangers, a state-level bureau of investigation. Walker was raised by his paternal uncle, an American Indian named Ray Firewalker (Floyd Red Crow Westerman, pilot episode, season 1; Apesanahkwat, season 2). The surname being, possibly, a nod to the 1986 Norris film, "Firewalker". Cordell, prior to joining the Rangers, served in the Marines' elite recon unit during the Vietnam War. Both Cordell and Uncle Ray share the values characteristic of Wild West sheriffs.
