- Adaptation Displacement: The short story's existence is sometimes overshadowed by this episode.
- Memetic Mutation: "It's a Good Life" is easily among the most famous and quotable Twilight Zone episodes of all time. It's real good that it is though. It's a real good thing.
- Nightmare Fuel: Everything about Anthony. He can do whatever he wants whenever he wants and if you don't agree worst things can happen to you. Twilight Zone: The Movie takes it Up to Eleven and makes him into a Reality Warper.
