"Junior Mastermind", also hosted by John Humphrys, is a children's version of the quiz programme and has the same format, the difference being that the contestants are only ten and eleven years old. The programme aired across six nights on BBC One, ending on 4 September 2004. The winner was Daniel Parker, whose specialist subjects were the Volkswagen Beetle (heat) and James Bond villains (final). There was another series in 2005 (subjects included Black Holes and the "Star Wars" trilogy), which was won by Robin Geddes, whose specialist subjects were "The Vicar of Dibley" and "A Series of Unfortunate Events", with a third series airing in 2006, won by Domnhall Ryan, and featuring subjects such as Harry Potter and Chelsea Football Club, and a fourth series in 2007 won by Robert Stutter and a fifth series later that year won by David Verghese. The Junior version was cancelled after the two 2007 series.
