Catch the beginning of the Twelfth Doctor's regeneration in the latest trailer for Doctor Who series 10
The latest little snippet of Doctor Who gives a lot of what we've seen before but for eagle-eyed viewers you can catch some new footage, include more Missy, more of the mysterious new female Ice Warrior and the return of the original Mondosian Cybermen.
But's it's that final shot that will certainly have fans excited, regeneration energy seeping from the hand of Peter Capaldi's Twelfth Doctor. Is this footage from the Christmas special or just one fake tease? Either way, we're excited.
Doctor Who series 10 return in just 12 days on Saturday 15th April on BBC One.
