Anyway they can make a more expensive one by adding all the Doctors played by currently living actors, the Doctor’s daughter, K9, Professor River Song, Ace and every other companion played by an actor who is still living, CGI versions of all the dead Doctors and companions, every former member of UNIT played by a still living actor… I’m sure there are lots more.

The only problem is would there be a good story in there trying to escape?

Yes, I know, but didn’t you think it was a good episode? (okay, Sarah Jane didn’t add much – this week – but there’s time yet).

And besides, it gives me at least six days during which to expect a phone call from the Beeb asking me to be the eleventh Doctor. It’s obvious when you think about it. They’ve never had an overweight boozy Geordie before*… “Haway man, Davros, just leave it like, now do you want another bottle of Broon or what?”

*for that matter, they’ve never had someone who isn’t a professional actor before. But if they want to give me a ring…
