Ncuti Gatwa rocks a moustache and long brown coat as the Doctor in the first images of him and Millie Gibson, who plays the Doctor's companion.
Ncuti is shown in pictures and video released by the BBC wearing brown check trousers and a matching coat with bright orange top underneath, while Millie is dressed in dark blue shorts, a short denim jacket and black boots.
Millie was announced as the latest Doctor Who companion when she stepped out of the Tardis live on Children In Need.
