The Twilight Zone became the role model for TV anthologies. The parables which usually resided in the world of fantasy or science fiction expertly explored humanity's hopes, despairs, prides and prejudices in metaphoric ways conventional drama cannot. Fully half of the episodes were written by Rod Serling, with other scripts penned by Richard Matheson, Charles Beaumont, Earl Hamner, Jr., George Clayton Johnson. Other talent on the screen 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, as well as such established stars as silent-film giant Buster Keaton, Art Carney, Mickey Rooney, Ida Lupino and John Carradine. Directors include: Richard Donner, William F. Claxton, Alvin Ganzer, Don Medford, Robert Parrish, Stuart Rosenberg and Elliot Silverstein. The series was nominated for seven Emmy Awards and four Hugos and won three of each.
