Jason Mamoa admits he hasn't yet seen his new movie, Darcey Bussell reveals she was overwhelmed receiving her damehood, Bill Bailey says rumours of his death were greatly exaggerated and Little Mix performs live in the studio.

Jason Mamoa, talking about Aquaman, says: "It's very exciting - I don't think we've ever gone under water quite like this before. It's very new. Technology and CGI have been taken to a whole other level." Adding, "I was a guinea pig this time so now we'll figure out how to make it even better."

Admitting he hasn't yet seen the movie, he says, "Here's the thing. I have two babies aged 10 and 11. They were on set for the whole filming and they made me promise them that I wouldn't watch it until I can watch it with them. I want to share it with my children and sit and hold their hands - it's a rare moment for a father and generally, they can't watch the things I do!"

Asked when he first found out he would play the role, he says, "2013 and I was literally broke - but the future would be bright! I couldn't say anything to anyone for years and I can't keep a secret to save my life. It was very hard for me so, I am glad we are now here."

Revealing that acting roles dried up after Game Of Thrones, he says: "I didn't get much work after that. I mean, what do you do with that - he (his character) doesn't speak English, he's not funny and he just hurts people. I played that character well so it was a bit challenging afterwards. People would literally say, 'Wow, you speak English!'"

Demonstrating his selfie techniques with fan couples, Jason poses with Darcey Bussell by literally keeping Bill Bailey at arm's length.

Darcey, talking about receiving her damehood, says, "I got two medals - it's really cool but I did drop one and was terrified I was going to damage it before I'd had fun wearing it. I had no idea who was going to present it to me beforehand. But, it was The Queen and she doesn't do them that often. I was very excited because just two people in front of me was Paul McCartney. I'm not sure what he was getting and I didn't get a chance to ask him. I was overwhelmed!"

Asked about her new book Evolve, which spans her ballet career, she reveals not everything goes to plan, "Once when we were performing outdoors in Israel and it was so hot. The lino we were performing on and our pointe shoes were literally melting. During the show, my shoes started to buckle and I had to turn 32 times. I was literally on my knuckles but had to keep going and panicking that I wasn't going to make it."

Talking about the upcoming grand-final of Strictly, and the seemingly endless scandal surrounding the series, she says, "There's probably no more than there usually is. It's just unusual for people to be so tactile and not to think you are coming on to them - it's the job and dancers are used to it but perhaps other people get the wrong idea." Asked what tips she might give a married person taking part in the next series, she adds, "I'm only there to judge!"

Bill Bailey, asked if he would ever do Strictly, says: "I've been asked a couple of times. I like the idea of the dancing but it is so judgemental, which isn't for me. I'd like to learn to dance without the critique. It's pretty harsh and withering."

Darcey assesses his potential to be a dancer from his walk and critiques the Prime Minister's various dance moves.

Bill, talking about rumours of his untimely death, says, "I was mistakenly reported as dead on the BBC website. It just said, 'tributes are pouring in for actor and comedian Bill Bailey who has died at the age of 52.' It was really annoying because they got my age wrong! And, they used a weird photo of me. It was a bit of a shock to read it on Twitter. The real story was that a DJ in Kentucky called Bill Bailey who died and what I think happened was that someone at the BBC saw he had died and panicked. The funny thing was that my tour manager called me and said, 'Are you alright?'"

Asked about his new tour, Bill says, "It's about where comedy takes you. It's been all over the world, even to the North Pole. You have to have a gun with you there because Polar Bears rummage around the town. It's the most extraordinary place. I was walking through a glacier, which was amazing and suddenly got a text from my local chemist to say my medication was ready - it was so surreal."

Little Mix perform Think About Us, before joining Graham for a chat about their new album and upcoming tour. Talking about their fan base in Japan, the girls demonstrate that they know the words to their songs in Japanese.
