The team that worked on "Labyrinth" was largely assembled from talent who had been involved in various other projects with the Jim Henson Company. Veteran performers Frank Oz, Dave Goelz, and Steve Whitmire operated various puppets in the film, as did Karen Prell, Ron Mueck and Rob Mills who had all worked with Henson on "Fraggle Rock". Kevin Clash, a crew member on "Sesame Street" best known for voicing the character Elmo, worked on the film. Members of Henson's family also worked on the production, including son Brian and daughter Cheryl. Newcomers working on the production included puppeteers Angie Passmore and Anthony Asbury, who had previously worked on the satirical puppet show "Spitting Image".
