The series featured former The Young Ones stars Nigel Planer, Rik Mayall and Adrian Edmondson as its three title characters respectively. It was written by Ben Elton with additional material credited to Mayall. One series of six half-hour episodes was produced (although the notion of a second series is played upon in the final episode, and the continuity announcer on the last installment says "...and Filthy, Rich and Catflap will return next year." They didn't.)
