 Although the series was judged a success, the departure of both Sydney Newman and Irene Shubik to the BBC meant that a second season was not made.However, while at the BBC Shubik devised and produced "Out of the Unknown", another science fiction anthology series that, like "Out of This World", concentrated mainly on adaptations of short stories and novels and ran for four seasons between 1965 and 1971.Two "Out of This World" scripts — "The Yellow Pill" and "Target Generation" — were remade by "Out of the Unknown" in its third season.
