You probably know that HBO’s hit new series Westworld is based on an old movie, also named Westworld, written and directed by Michael Crichton. But did you know there already was a Westworld TV show? After Westworld became a hit in theaters (and after a sequel, Futureworld, a few years later), CBS aired a series called Beyond Westworld. The show wasn’t nearly as successful as the new Westworld; only five episodes were produced, and just three aired on television. So with its first season finale days away, the new Westworld is already much more successful than the last one. That’s just one of the facts packed into the latest episode of the ScreenCrush series You Think You Know TV?
