Previously unseen film footage of the real life Christopher Robin will be screened tonight, 72 years after it was shot.

The ten-second film shows nine-year-old Christopher Robin Milne, son of Pooh author AA Milne, taking part in a pageant in Ashdown Forest in 1929.

It will be shown on The Real World Of Winnie The Pooh at 7.30pm on BBC2 in the South East.

The film was discovered by a BBC producer researching the documentary to celebrate the 75th birthday of the famous bear.

Christopher Robin even referred to the pageant - in which he followed children dressed as Winnie the Pooh, Piglet, Eeyore, Tigger and Kanga - in his autobiography.

However, he was not aware of the film.

He said in the book: "The pageant went its memorable way and I see it as a ancient cine film, much faded and blurred and with many breaks, but with here and there a sequence as vivid as the day it was shot."

BBC producer Helen Kent, who discovered the film while searching for footage of Ashdown Forest in the Twenties, said: "I couldn't believe I had discovered actual footage of the real Christopher Robin Milne."

Frank Gray, director of the South East Film and Video Archive said: "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."
