Season 10, Episode 04 – Knock Knock
Bill is moving in with some friends and they’ve found the perfect house! So what if it’s strangely cheap to rent, and the landlord is a little creepy? The wind blows, the floorboards creak and the Doctor thinks something is very wrong. What lurks in the strange tower at the heart of the building – and why can’t they find any way to enter it..?
The Doctor is an alien Time Lord from the planet Gallifrey who travels through all of time and space in his TARDIS. He has a long list of friends and companions who have shared journeys with him. Instead of dying, the Doctor is able to “regenerate” into a new body, taking on a new personality with each regeneration. Twelve actors, plus John Hurt, have played The Doctor thus far.
