Harry Enfield, Tim Vine, Dale Winton, Simon Callow will also take part in the irreverent take on the popular drama about life above and below stairs in the Edwardian era.
Victoria Wood plays "Mrs Crawler" and Joanna Lumley the housekeeper figure. The sketch will apparently reveal how much of a flirt Lady Mary really is, and whether Thomas the dastardly second footman is as catty off camera as he is on it.
