Episode #5: "The Sixth Finger"
5 / 5
Actors include: David McCallum, Jill Haworth, Edward Mulhare
This is an iconic tale about a scientist who develops a super intellect formula. He tests it out on a miner who's intellect grows, along with the size of his head. He becomes so brilliant that he masters mind control and starts to become dangerous. It's really an interesting episode that you've likely seen spoofed different places, definitely one to catch.
Episode #6: "The Man Who Was Never Born"
4.5 / 5
Actors include: Martin Landau, Shirley Knight
An astronaut turns up 200 years in the future to discover that mankind is only a few mutants who survived a biological disaster. He finds out who is the cause, and tries to travel back in time and correct the problem, but of course some different things go unexpectedly because when you change one thing in the past or future, other things change too. Very cool story that has likely made films like "The Butterfly Effect" and "Back To The Future" possible.
