12.23pm: As usual, the timings in this panel are PT, which is eight hours behind the UK and three hours behind the East Coast.
12.24pm: Expected at this panel are Matt and Karen, as well as writer Toby Whithouse and outgoing exec producers Piers Wenger and Beth Willis.
12.25pm: BATTERY LIFE UPDATE: 45%. We'll be fine.
12.26pm: MOOD UPDATE: Were it not for the fact I just used the restroom, I would be wetting myself with excitement right now.
12.27pm: This is quite cool. The crowd have started an applause in the style of The Master's rhythmic tapping.
12.30pm: There's a sea of sonic screwdrivers in the air over the far corner of the room.
12.31pm: Americans behind me talking about classic Who versus new Who. "It was very good in the 70s," says one. "It was so campy and funny. Little aliens would come on and you could tell it was a piece of plastic."
12.32pm: The moderator for this session is Adam Rogers, editor of Wired magazine.
12.33pm: We begin with a clipreel of the highlights from the first half of the season.
12.37pm: Out come the execs, along with Matt and Karen.
12.38pm: Matt gets excited seeing Daleks in the crowd. "It's the first time we've been here. It's completely overwhelming. The levels of enthusiasm and passion - the costumes. We saw a great weeping angel earlier. Look at all the fezzes and stuff."
12.39pm: Gillan on the River twist: "I never thought that would happen. My mum's quite excited that she's Alex Kingston's grandmother."
12.40pm: When did they know about it? Gillan: "We had a dummy ending on the actual script for the readthrough. Then Steven took us out and showed me, Matt and Arthur the real ending. We started running up and down the corridor. Only Alex knew." Smith: "She wouldn't tell us. Steven gave her more power. How can you give River Song more power? It's not fair!"
12.41pm: Matt says they have "some real huge cliffhangers coming up" as well.
12.42pm: Whithouse: "The thing about this show, it's so engrained in the English consciousness. It's massively important. It's a phenomenon in the UK." Smith: "It's really exciting for us that it's growing so much in America."
12.43pm: Smith corrects the moderator, who claims the Christmas special got 20m viewers in the UK. "It was more like 12, but that's huge for England." I HOPE HE'S COUNTING IPLAYER USAGE, EH STEVEN?!?
12.44pm: Whithouse speaks about his excitement about writing an "INT. TARDIS" scene. Willis recalls that in Gaiman's script, he wrote a dummy line "I've been waiting my whole life to write this." after his first "INT. TARDIS" mention.
12.45pm: Willis: "For Piers and I, we've been with Matt the whole time, so Matt is our Doctor. I can't imagine anyone else doing it."
12.46pm: Clip from Toby's episode. Tied up boy saying "Bring me death, Bring me glory." Rory with a MOP (huge cheer), Amy trapped in a room with a sad clown with an umbrella. Beast stalking the corridor. The Doctor killing the power and saying "That's quite enough of that."
12.47pm: Whithouse says it's called 'The God Complex' and is episode 11.
12.49pm: Resolution to the astronaut thing in the second half? Whithouse: "The one downside of working on Doctor Who is that you learn things in advance. I knew about who River Song is months in advance, because there was one line in 'The God Complex' that I had to know for."
12.50pm: LAUNCH DATE CONFIRMED: Aug 27 on BBC America.
12.51pm: Clips from second half of season. You'll see it soon enough, but the main thing: river wearing an eye patch! Also Churchill, Corden back. Hitler thanking them for saving his life.
12.52pm: Audience questions. First one comes from an actual Dalek, who we have trouble hearing. Will the Daleks be back? Wenger: "There is only one word that can answer that question, and that's 'spoilers'."
12.53pm: Please no.
12.54pm: Someone mentions Chameleon Circuit, who've charted on the Billboard chart (well done, boys!). Smith: "Can you just tell me what the Chameleon Circuit did?" The questioner explains and suddenly it clicks. Karen is excited. Smith: "Charlie's great. He's getting a million hits on YouTube and stuff. I think we're lucky to have someone like him championing our show and spreading the Who love."
12.56pm: A very enthusiastic Russian lady, presumably with hairy armpits, asks if John Barrowman will be back and what pranks they play on set. Karen says that Matt hides in her trailer with a loud horn to scare her.
12.57pm: Will there be another multi-Doctor story? Whithouse: "You'd have to ask Steven that but yeah, why not? Come on, let's bring them all back."
12.58pm: Another Dalek decides to exterminate the panel and then asks if the Doctor's daughter will return. Wenger: "Well we've just had The Doctor's Wife." Smith: "Who knows? Again, that's a Steven Moffat again, so you never know." Gillan: "Didn't she die at the end of that episode?" Willis: No! Russell left that open." Smith: "She survived. And then she married The Doctor."
1.00pm: Will we see the Dream Lord again? Smith: "He's one of my favourite actors. I'd love to get him back, with a bigger army behind him. If you look at the blood on The Doctor's hand over the ages, there's so much of it."
1.01pm: Does Matt know what the controls in the TARDIS do? Smith: "When I turned up on the first day, they gave me a manual. If you look at the takes of taking off and landing, it's always the same thing. The TARDIS never gets boring, ever."
1.02pm: What is their favourite alien race? Gillan: "I really liked the Sisters of Plenitude. You know, the cats. The nurse cats." Smitgh: "I'm into the Sisters of Plenitude, absolutely. The Weeping Angels are my favourite."
1.03pm: Excluding Matt, favourite Doctor? Wenger says Tom Baker. Willis goes for Tom Baker too. Whithouse says Baker or Tennant. Gillan: "I liked Chris Ecclestone." Big applause. Smith says he liked Troughton.
1.04pm: Do they ever consider themselves as contributing to the creativity of modern storytelling? Wenger: "No, we don't, because if we did, we'd be a bunch of arses, wouldn't we? But we do take this show seriously. It is our lives and we want to make it brilliant."
1.06pm: Willis: "Every time the Doctor regenerates, having a woman will always cross the mind of whoever's running the show." Wenger: "A little bit of me thinks that maybe River has stolen the thunder of having a female Doctor."
1.07pm: How much of himself does Matt put in the Doctor and vice versa? Wenger: "We're better placed to that one! What you see on screen is pretty bloody close to what you see in real life. Except he's not as competent as The Doctor. One of Steven's favourite things to say after the fourth glass of wine of the night is, 'he just is The Doctor'." Smith: "I just wish I was as cool as him. It's like, Amy Pond is way cooler than Karen." Gillan: "That's true!"
1.09pm: Audition process. Smith: "Everything's top secret. You get the script a day before. You go in and do your thing. Weirdly, when David was leaving, my mum texted me and said 'you should be the next Doctor'. I'll never forget when I got the call. I was in Aldgate, coming back from an audition on a cold street, and it's a life-changing moment. It was remarkable." Wenger: "It's the easiest casting decision I've ever been involved in, because it was so bleeding obvious from the moment he walked in the room. I remember the day after we'd met for the second time, I got an email from Steven that just said 'It's him. Let's face it, it's always been him.'" (ooh, Torchwood reference?!)
1.12pm: Any acting advice for a newbie who's just beginning theatre training? Gillan: "Attend. That's always good. Then I guess do your training, soak up everything you can…" Smith: "Read as many plays as you can, see as much theatre as you can. Also be brave. Make brave choices creatively."
1.13pm: A girl called Melody asks if they research the science much. Willis: "Errrr." Whithouse: "A childhood spent watching Hammer Horror films. In a way, Steven came up with the perfect, spacey-wacey, time-wimey thing, which is a great coverall. For 'The God Complex', I did a lot of research into Greek mythology, for reasons which will become apparent."
1.15pm: Did Matt expect the Fez to catch on? Smith: "That's one of those things you have no idea about. All testament to Steven Moffat for having the ingenuity there. What's cool about that is it's me bleeting on to him about me wanting to wear a hat, and he gave me the most stupid hat he could think of." Gillan: "It's only on screen for a short period of time!" Smith: "Yeah, and then River blows it up! It's all about the stetson now, though."
1.17pm: Why did they make the sound of the TARDIS like they did? Willis: "There's a reference to that in one of your early episodes." Smith: "That came long before our tenure, but Steven reinvented it in a knew way, which is that The Doctor is flying it wrong, with the brakes on. But it still makes that sound anyway. That's a question for a Doctor of old."
1.19pm: Why do they keep killing Rory? Smith: "But we keep getting him back." Willis: "And he learns a lot every time he dies. The guy that waited."
1.20pm: How do they manage to keep secrets? Gillan: "My secret, I've still got. And you still don't know it." Smith: "Steven's told Karen something about… we can't even say what it's about." Gillan: "It's so exciting! I feel so powerful now." Smith: "She's told me what it's about, but she won't say what it is."
1.21pm: How many props have they broken? Smith: "Me. It's a daily process. Phil the props guy does a fantastic job. I tend to break a sonic screwdriver a day, because I'm all clumsy. And bits of the TARDIS are falling off."
1.22pm: If they could cross Who with one other show except Torchwood, what would it be? Smith says True Blood, while Gillan shouts Star Trek: TNG enthusiastically and recalls being excited at meeting Data last night.
1.23pm: How do they reach the future screwdriver and what does the red setting do? Smith: "That's River's screwdriver. Frankly just the fact she has a screwdriver annoys me. I dismiss it as a useless one. The only one that counts is The Doctor's. The red setting turns you into an orangutan."
1.25pm: How much is River based on Bernice Summerfield from Big Finish? No-one knows.
1.26pm: Will we see more of The Doctor's dark side? Smith: "I hope so. As I said earlier, there's a lot of blood on his hands, and I think that's why he's so bubbly and cheery, and has to keep going. If he didn't, if he stopped, he'd have to contemplate losing all these people. I think there'll be a lot more." Gillan: "I think in episode ten, we see some of The Doctor's dark side. rule number one: The Doctor lies. That's going to be explored."
1.27pm: Who would they want to write an episode? Matt says Edgar Wright or "JJ Abrahams". Karen says Roald Dahl, while Toby says he wants to see Russell come back for an episode.
1.28pm: Matt asks the crowd to give a cheer for Wenger and Willis, who are leaving the show.
1.30pm: After another play of the trailer, that's a wrap on this panel. And this also marks the end of my guest return to DS for this year's Comic-Con coverage. It's been an absolute blast - I hope you've enjoyed it too. See you soon!
