The Tale of Peter Rabbit
In 1992, several of Potter's tales were adapted to animation and televised by the BBC as "The World of Peter Rabbit and Friends". In an episode that integrates "The Tale of Peter Rabbit" with "The Tale of Benjamin Bunny" called "The Tale of Peter Rabbit and Benjamin Bunny", Mr. McGregor is voiced by Richard Wilson and Mrs. McGregor by June Watson. In "The Tale of the Flopsy Bunnies and Mrs. Tittlemouse", Mr. McGregor is voiced by Andrew Robertson and Mrs. McGregor again by June Watson. In this episode (with no basis in Potter), Mr. McGregor's first name is given as John.
