The original series was created by Sam Rolfe and Herb Meadow and starred Richard Boone as the San Francisco gunfighter Paladin, who had high-class taste but was still a total badass despite a slightly frou-frou taste for chess symbolism. "Have Gun - Will Travel" ran for 225 episodes, one of which was written by Sam Peckinpah, and 24 of which were written by "Star Trek" creator Gene Roddenberry. A potential movie remake has been bouncing around in development for a while, first with John Travolta attached to star and later Eminem.
Mamet will serve as writer and executive producer on the reboot, and he'll direct a pilot if one's ordered. Elliott Webb is also serving as an executive producer.
This isn't Mamet's first venture into television -- he created and served as a writer and executive producer on military drama "The Unit," which ran on CBS from 2006-2009. Mamet also wrote an episode of "Hill Street Blues" and wrote and directed HBO's upcoming Phil Spector movie starring Al Pacino as the infamous producer.
