The Zygon Inversion – Doctor Who Series 9 Episode 8 preview videos

The Zygon Inversion

The Zygon Inversion is the eighth episode in Doctor Who Series 9, and concludes yet another two-parter, again featuring… The Zygons, a race of shapeshifting aliens, who have been living in secret amongst us on Earth, unknown and unseen – until now! Well… last week.

Shapeshifting Zygons are everywhere in the UK, and there is no way of knowing who to trust. With UNIT neutralised, only the Doctor stands in their way. But how do you stop a war? And what can the Doctor do to save his friends?

As well as the trailer, below you can check out an introduction to the episode, Steven Moffat’s teaser for the episode, plus two clips – Good Clara Vs Bad Clara and Where’s Clara?

The Zygon Inversion is written by Daniel Nettheim, responsible for Kill The Moon (yes, the moon was an egg!), with a co-writer credit from Steven Moffat, and directed by Daniel Nettheim.

The episode also stars Jemma Redgrave, Nicholas Asbury, Aidan Cook, Tom Wilton and Jack Parker.

The Zygon Inversion is broadcast tomorrow night on BBC1 at 8pm, and then on BBC iPlayer afterwards.
