The Twilight Zone
Hosted by the iconic Rod Serling from 1959 to 1964 on CBS, The Twilight Zone is science fiction television at its best. Each episode tells a new story of strange happenings. In the everyday world, these things would be impossible — but when one accidentally crosses over into the Twilight Zone, anything can happen.
Maybe the best episode is “Nightmare at 20,000 Feet,” starring William Shatner as a man who is recovering from a nervous breakdown when he sees a strange little alien man standing on the wing of the airplane he’s on — except no one else can see the man but him.
