Step behind the camera with presenter Steffan Powell in the first of this access-all-areas series. We catch up with David Tennant and Catherine Tate ahead of their much-anticipated reunion and meet the monsters and makers of The Star Beast. We also get a very special tour of the new TARDIS from the Doctor himself.

Steffan Powell goes behind the scenes of The Giggle and speaks to the Toymaker, Neil Patrick Harris. We meet the fifteenth Doctor, Ncuti Gatwa, and find out what it's like to become the Doctor for the first time.
