The final series for ITV had Millicent Martin in every episode. This was because ATV were introducing Eric and Ernie to an international audience and Millicent Martin was more well known around the world than they were.
This was Morecambe and Wise's second attempt at television. Several years earlier they had made their tv debut in Running Wild for the BBC but the reviews and ratings were terrible and the series was cancelled after just six episodes. They returned to stage work to rebuild their act and reputation and returned, much more successfully, for this series, this time on ITV.
