the Movies. Additionally, several guest stars from the series had cameos in the first three Muppet theatrical films, and season four guest Alan Arkin cameoed in The Muppets. Originally, the producers had to call on their personal contacts to appeal to them to appear, especially considering that doing so required an overseas trip to Britain. However, the situation changed when the renowned ballet dancer Rudolf Nureyev offered to appear; his performance on this unusual TV programme produced so much favourable publicity that the series became one of the most sought after for various celebrities to appear in.

The next year, Peter Sellers—who chose not to appear as himself, instead appearing in a variety of characters— and Bernadette Peters earned nominations for the same award. One episode featured staff writer Chris Langham (who wrote some episodes of this show, starting in the third season) guest-starring due to Richard Pryor being unable to make the taping of the episode at the last minute. An early tradition was to present the guest star with a Muppet likeness of themselves as a
