I saw this on TV when I was a kid. The basic idea seemed directly lifted from the movie, Forbidden Planet. The Leslie Nielsen captain character was played by a good looking, charismatic actor, and the cerebral Warren Stevens doctor character was covered by a cerebral second officer character and a conscience-driven doctor character. The ship was run like a large naval vessel, but traveled around the galaxy at super-luminal speeds. Some of the episodes were similar plot-wise to the movie in that the ship would visit a planet inhabited solely by a Walter Pidgeon type loner character and a beautiful young woman (Anne Francis) character.
Did the concept of StarTrek originate from Forbidden Planet or was Forbidden Planet itself derivative of an earlier SF story (book, short story, movie, or other form)?
