All day today, there are more Doctors in the house. Today is the penultimate day of the Doctor Who takeover week, and it includes a new special, at 9 p.m. ET, called Doctor Who: Earth Conquest. It follows the actor playing the imminent 12th Doctor, Peter Capaldi, as he embarks on a seven-city, five-continent, 12-day tour to promote the new incarnation of Doctor Who. Fittingly, accompanying him on this whirlwind publicity tour is Jenna Coleman, the actress playing the Doctor’s current (and near future) traveling companion. Expect one or both of them, sometime in this hour, to suggest that they could have used a real TARDIS to make their journey easier.
