Kathryn Mullen is an American puppeteer, actress, and voice actress most closely associated with Jim Henson projects.

The Muppet Show is a variety sketch comedy television series created by Jim Henson and starring the Muppets. The series originated as two pilot episodes produced by Henson for ABC in 1974 and 1975. While neither episode was moved forward as a series and other networks in the United States rejected Henson's proposals, British producer Lew Grade expressed enthusiasm for the project and agreed to co-produce The Muppet Show for the British channel ATV. Five seasons, totalling 120 episodes, were broadcast on ATV and other ITV franchises in the United Kingdom and in first-run syndication in the United States from 1976 to 1981. The programme was produced and recorded at the ATV Elstree Studios in Borehamwood, Hertfordshire.
