David Tennant hosts a special edition of the quiz show with team captains Phill Jupitus and Noel Fielding. The guests are actor Bernard Cribbins, who stars as Wilf Mott in the episodes that see the 10th Doctor regenerate into Matt Smith, and actress and former Time Lord's companion Catherine Tate. In non-Doctor related guests, we have platinum-selling jaaaaaaaaz musician Jamie Cullum and Radio 1 DJ Jo Whiley. There might also be the odd Dalek popping up here and there.
