The clips from Lost in Space episodes shown were: "No Place to Hide," "The Mechanical Men," "Condemned of Space," "Visit to a Hostile Planet," "The Promised Planet," "Fugitives in Space," "The Great Vegetable Rebellion," and "The Anti-Matter Man."
John Larroquette along with the Lost in Space Robot hosted the episode.
Robot: (joking around about his cast mates' success, and his career ending after Lost in Space) In fact, Irwin had plans to give me my own sitcom, Rodney the Robot, a cross between Three's Company and My Mother the Car.
The end title theme was performed and arranged by Bill Mumy.
This episode is in an entirely different format than the other episodes of The Truth Behind the Sitcom Scandals. In fact, "Lost in Space Forever" was originally a special a decade ago. The Truth Behind the Sitcom Scandals just aired it as if it was an episode.
A clip from the short-lived Lost in Space cartoon is shown.
Lost in Space Forever is available on DVD.
