WATCH: The Doctor’s new companion Bill in action in first official series 10 trailer!

The first official Doctor Who series 10 trailer – and proper glimpse of new assistant Pearl Mackie in action as Bill – has arrived online.

The trailer first aired after Christmas Day’s fantastic festive special ‘The Return of Doctor Mysterio’, revealing the series to return in April 2017. However, if you happened to miss that after popping out for a turkey sandwich or succumbing to a booze-fuelled slumber in front of the telly, we’ve got the whole thing here:

The new trailer is narrated by Bill, the Doctor’s new permanent assistant. In the 50-second clip, we learn Bill serves chips at a canteen and knows the Doctor as a university professor. We’re not quite sure what the Doctor is doing as a university professor in the new series, but we are sure that boffin would be rather good at it.

As expected, Bill is promptly thrown into the thick of the action in the Tardis. She thinks the Tardis looks like a kitchen, and she has got a hell of a lot of questions about the whole time-travelling thing.

We also get a peek at some of the landscapes we’ll be visiting in series ten, which may be Earth or elsewhere (but were almost certainly filmed in Cardiff, either way) plus some alien adversaries. Yes, there are Daleks.

After last night’s ‘The Return of Doctor Mysterio’, we really can’t wait!
