Richard Curtis, the man behind Notting Hill, Love Actually, Four Weddings and a Funeral and, perhaps more relevantly, Blackadder is to write an episode of Doctor Who. "There will be a monster. And a famous historical figure will battle the monster," Curtis says.
Curtis says he was persuaded by his children and has an interest in time travel (he has a film in the pipeline). But who would you try to persuade to write for Doctor Who? And how would you tempt them?
Recent writers include - of course - Russell T Davis, previously known for Queer as Folk, Mark Gatiss, whose credits include the League of Gentlemen and a number of novels, and Steven Moffat, lead writer for the coming Doctor Who series starring Matt Smith.
So you don't need to restrict yourself to writers working in genres close to Doctor Who - Richard Curtis doesn't appear to have done much tangling with Cybermen. And let's cast our nets wider than television too: novelists who might fit the bill, comedians perhaps - people who might bring something different to Who perhaps. (Or is that sacrilege?)
