Got a chance to post more about the night with Capaldi now.
Full house with lot's of people dressed up. Most impressive I saw was a girl in our row dressed as the tardis, complete with light on top of her head (glad I wasn't sitting behind her). I had a Doctor Who t-shirt with Capaldi on the front.
Format was some Australian guy interviewing him and I guess most of it was scripted as they would have done the same thing at the Sydney Dr Who festival last weekend.
Some interesting bits I can remember:
On getting the part: He got a call from his agent asking how he'd like to be the next Doctor and he went along to Moffat's house for an audition which turned out to be a regeneration scene. He thought he would probably be one of many but it turned out it was just him as Moffat really wanted him, but it had to go through so many levels even as far as the Director General of the BBC having to sit down and watch his audition, so it took a long time from audition to getting it. While he was in Prague filming The Musketeers he got a call from his agent saying simply "Hello Doctor." He wasn't allowed to tell anyone and while he was being put into costume the costume guy commented "you seem to be somewhere else today My Capaldi." As he couldn't say anything he spent a few days walking around Prague humming the classic theme tune. He hadn't been on a lifelong crusade to get the part like the media said, it just sort of happened. When asked if he ever thought of not taking it he said only for about 10 seconds when he thought of how much extra attention he'd get from the press but DOCTOR WHO.
On his role in the Pompeii episode: He got sent a script and said "I have to do it" without even looking at it. His wife said "you're a professional actor, you have to at least read it."
On how big Dr Who is worldwide: He didn't realise quite how massive it is. On the tour they did for last season they went to (I think) Korea and when they got off the plane it was like they were the Beatles.
On funny moments on set: He was filming Mummy on the Orient Express while Jenna was filming Flatline separately since he was not in Flatline much and she wasn't in Mummy that much. She sent him a video of her singing "All by myself" as a joke so he and the crew sent her back a video singing "Thank you for being a friend" from the Golden Girls. They showed the video of this on the big screen and it was like a terrible karaoke video where none of them knew the words.
On Moffat: He has a full size Weeping Angel in his garden so he can tell whether his visitors are Whovians, as they immediately run the other way! At the Sydney festival there was a Doctor Who themed pub quiz so he, Moffat and Mark Gatiss entered as a team called "The Last Time Wasters" assuming they would easily win but they came third. They showed video of them finding out they'd lost and he said Moffat was pissed off, going around for an hour after saying "I can't believe I got that one wrong." Said Moffat even got some questions wrong about scripts he had written!
On filming highlights: The standout was the first time he worked with the Daleks in Into the Dalek. This short guy who goes inside the Daleks came up to him and said in a very posh voice "would you like to rehearse the scene?" "But there's no dalek." "Well I'm the same height as a dalek so just pretend." Then the guy who does the Dalek voice turned up and they rehearsed the lines. They they got a dalek, connected up the lights and the voice box and did it for real "and it was Fabulous!"
On the guitar: He was given the job of buying the Doctor's guitar so he went to some famous guitar shop in Soho and tried them all, then went with what he thought it would look like if the Doctor designed one not knowing what a Fender Stratocaster looked like (what he got is actually a Yamaha). He learned to play the middle part of the theme tune that's not in the current one so that's what he plays.
On the sonic glasses: It was because he doesn't have his own screwdriver yet and was using Matt's. Hinted that "fans of the sonic screwdriver should not despair."
On how hard the role is physically: Told how he met up with Matt Smith for some advice and Matt turned up on crutches saying "this show mate, it ruins you." Then he got the exact same knee injury and had surgery 4 weeks ago. He demonstrated how it happened by running across the stage and quickly stopping and turning around.
On Clara's death: He said she was originally leaving last season and then again in the Christmas special but he and Moffat kept managing to convince her to stay so several episodes had to be rewritten. But this time she had to leave as she's is doing the Queen Victoria thing. On her departure he said something along the lines of "what happened was not a lie, the story is the story but the Doctor won't let it rest and cannot accept that's the last time he will see Clara." Possibly hints she may appear in some form in the season finale.
On the next episode: It's unique that it only features the Doctor and is a very scary episode.
He also showed how much of a Doctor Who geek he is with a lot of knowledge of classic episodes. One moment that stoodout was a boy who got picked to ask a question said he was dressed as "the 4th Doctor, specifically from the episode with the Mona Lisa" to which Capaldi immediately said "City of Death."
Those are the main bits I can remember.
Funny he mentioned that about the screwdriver, because a picture from Hell Bent leaked. And its the new screwdriver.
