One of TVs most revered Sci-Fi series, The Twilight Zone (CBS, 1959-64) stands as the precursor for TV anthologies.
A majority of scripts were written and produced by creator Rod Serling along with now-legendary writers such as Richard Matheson and Charles Beaumont. The series also featured such soon-to-be-famous actors as Robert Redford, William Shatner, Burt Reynolds, Robert Duvall, Dennis Hopper, Carol Burnett, James Coburn, Charles Bronson, Lee Marvin, Peter Falk and Bill Mumy, along with such established stars as silent-film giant Buster Keaton, Art Carney, Mickey Rooney, Ida Lupino and John Carradine.
The Twilight Zone ran from 1959-64 but was replaced for half a season in 1962-63. The series was then brought back for 18 episodes in a one-hour format. They would return for one more full year in the half hour format, being canceled at the end of the 1964 season. Four decades later the Twilight Zone remains as a truly classic series.
