Incidentally Moffat wrote some episodes for Murder Most Horrid with Vicar of Dibley's Dawn French. And he is the mastermind creator and writer for the BBC series Coupling, which (surprising to me) was inspired by his wife Sue Vertue, who worked on Mr. Bean, and his relationship before getting married. Getting back to Doctor Who, Moffat who wrote the really powerful episodes "The Empty Child"/"The Doctor Dances", which I thought were some of the best of the ENTIRE series, should don his producer's hat come sometime in 2009 for episodes to be broadcast in 2010.
