In Summer 2009 artist Nathaniel Mellors was commissioned by the BBC to make a short "work of modern art" to introduce the final episode of the series. The resultant work "The Seven Ages of Britain Teaser" features Dimbleby voicing a silicon mask cast from his own face, alongside actors Gwendoline Christie ( as 'The Operator') and Johnny Vivash (as 'Kadmus').
