Peter Capaldi is now officially stepping into the TARDIS as the Twelfth Doctor; see the men whose ranks he joins in bringing the cult sci-fi classic's Time Lord to life
William Hartnell's First Doctor was a professorial, and fairly irascible, gent although he gets big points for facing off against the dreaded Daleks in the show's second ever serialized adventure.
