From the Sun: Producers travelled back in time to pick out old footage of the actors. Three are now dead to appear in the Next Doctor Christmas Special.
Show chief Russell T Davies said: “It’s nice for fans to see the old doctors. And it helps kids get their heads round the fact there have been lots of them.”
The ten, from William Hartnell in 1963 to the latest David Tennant, will appear in The Next Doctor alongside new foes, the Cybershades. They are hairy, mutant cousins of the evil Cybermen — but they’re not the only enemy the Doc faces.
