The BBC said Monday that it had unearthed a 10-second clip of the real Christopher Robin Milne trailing a group of children dressed as Winnie the Pooh, Piglet, Eyeore, Tigger and Kanga for a school pageant in Ashdown Forest in 1929.
Christopher Robin was nine at the time, but was to write about the event in his autobiography later in life: "It was exciting doing my bit."
The clip is included in a documentary, The Real World of Winnie the Pooh, set to air on the BBC tonight.
Frank Gray, director of the South East Film and Video Archive where the clip was found, told the BBC, "This is the only film we have of Ashdown Forest from that period, so for this one film to be the film that also showed Christopher Robin was virtually impossible. It's a wonderful piece of film because it links the world of Winnie the Pooh to Ashdown Forest and Christopher Robin."
