Hosted by Chris Hardwick, the hour panel comprised of showrunner/executive producer Steven Moffat as well as stars themselves Peter Capaldi, Jenna Coleman and Michelle Gomez - the latter two making their debut at the event. While there was a lot of crypticness in relation to upcoming plot points from the new series (amidst the banter and cosplays), a trailer was then released and here are some of the highlights ....
Not only are the Daleks back then (en masse, even with a 60s model) but going from the various shots in the trailer, it looks like both Karn and Skaro are also making their returns. It's likely for the opening story, The Magician's Apprentice/The Witch's Familiar. While also not officially confirmed, those Davros as a child rumours are also looking likely to be true, given that Peter Capaldi has revealed that the Doctor will help a war victim with disastrous results.
Keeping with the opening story, we had various shots of the Master/Missy in the trailer and between Michelle Gomez, Peter Capaldi and Steven Moffat, there's been a lot of interesting points made on the dynamic that Missy will have with the Doctor this series. She'll definitely be her evil self and no doubt has some kind of a role in the Dalek stuff this series but it also seems we're going to learn more about the Doctor/Master friendship as well.
In terms of other confirmations, it looks like Toby Whithouse's story will feature an underwater city/terrifying ghosts, there's a moment where the Doctor dons some shades and a guitar, some hugging with him and Clara, an alien with two faces as well as some child snatching Zygons. Surprisingly enough, we didn't actually get any clips of Osgood in the trailer though Steven Moffat has confirmed that there will be a 'tough love' element to her returning two parter.
What took you so long, old man? - And then there's Maisie Williams character from the connected episodes, The Girl Who Died/The Woman Who Lived. While the former episode has been confirmed as a Viking on a spaceship story, the latter one has Williams in highway gear, confronting the Doctor - whom she seems to have a history with. Moffat gave us no clues as to who her character will be but the robotic monsters will be named The Mire though.
As trailers go, it's definitely one of the best the show has done and has set up the tone for Series 9 pretty well.
