But you shouldn't be here at the same time, with him

How splendid that Doctor Who Confidential caught the moment that Matt Smith met Russell T Davies – the latter trying not to be in the way. Naw.

But it occurred to me after a Spitfire or two that there was no sign of Tennant and Smith being there at the same time. And that films of more than one Doctor are rare. Excluding Doctor Who itself, this is what m'colleague Will Howells reckons is the definitive list of multiple Doctors in film and TV:

• Escape (1948) – William Hartnell as “Inspector Harris”, Patrick Troughton as “Jim – a shepherd”
• Would Any Gentlemen...? (1953) – Hartnell as “Detective Inspector Martin”, Jon Pertwee as “Charley Sterling”
• Dial 999 ep 1.16: “50,000 Hands” (1959) – Hartnell as “Jeff Richards”, Troughton as “Tramp - uncredited”
• All Creatures Great and Small ep 3.4: “Hair of the Dog” (1980) – Troughton as “Roddy – uncredited”, Peter Davison as “Tristan Farnon”
• Jude (1996)- Christopher Eccleston as “Jude Fawley”, David Tennant as “Drunk undergraduate”
• Mrs Bradley Mysteries ep 1.1: “Death at the Opera” (1999) – Davison as “Inspector Henry Christmas”, Tennant as “Max Valentine”
