'I am a dedicated fan.' --- Michael Parkinson

The brilliant Dead Ringers return to haunt the worlds of politics and celebrity in another razor-sharp series of media mimicry.

As the BBC bids a solemn farewell to a much-loved national figure, across the pond George Bush is played by Russell Crowe in the new film A Beautificacious Mind. In Ambridge, Brian and Siobhan receive the tragic news that their baby will be voiced by Martin Jarvis, whilst on Crimewatch Nick Ross investigates the mysterious theft of a certain globe-shaped BBC balloon.

Elsewhere, Nigella Lawson gives a dire warning about the perils of buying dodgy used recipes, and the Doctor tries to place a small ad for his next assistant. George Lucas' latest blockbuster tells of a young boy named Blair who dreamed of saving the galaxy, and Dale Winton ropes Graham Norton and Barbara Windsor into some showbiz coverage of the local elections.

Jon Culshaw, Jan Ravens, Mark Perry, Kevin Connelly, Phil Cornwell and Stefano Paolini give us their impressions of the people we love to laugh at in four ferocious episodes.
