Tom Cruise doesn't rule out Top Gun II, Emily Blunt says working with Tom was overwhelming, Charlize Theron talks about her first movie and Seth MacFarlane discusses his many alter ego voices. Coldplay performs live in the studio.

Tom Cruise, talking about his new film Edge of Tomorrow, says: "It's a totally different character. I've never played a coward before but dying over and over again becomes a lot of fun as you try and work out different ways to die - it was like playing Wile E Coyote. The deaths became funny and I worked for a year on all the different screams!"

He reveals becoming an actor wasn't the first time he'd tried dangerous stunts, "I saw Evel Knievel jumping off a canyon and I lived on a steep hill so set up boards and trash cans to copy him. I was about eight years old and my sisters begged me not to do it, as I had been the hospital a few times by this point. I realised half way down the hill that I couldn't stop and it was too late to bail - I was committed and I thought I'm going to go so far and so high but of course the boards split and I ended up just pile-driving through the cans. It was violent and there was blood everywhere. My sisters were standing over me with no sympathy, just, 'We told you. You're in so much trouble.' My poor mother! She was very patient."

Confirming there will be a Mission Impossible 5, Tom says, "We are working on that right now," and reveals, "We will be shooting it here in London. We love it here."

Reluctant to be drawn on a sequel for Top Gun, he says, "I don't know. People have been talking about it but it's no closer to being true, but we have been talking about coming up with a story and a script - we'll see."

Emily Blunt, revealing she was overwhelmed by Tom, says "When I first started working with him I kept saying, 'Oh my god, it's you!' Then the illusion kind of wears off."

On getting into shape for her role, she says, "It was really physical but it was cool training. I did all kind of stuff. Sprinting, weight training, yoga and Krav Maga, the Israeli martial art - it's pretty aggressive."

Talking about being pregnant during filming, she says, "For some additional photography I was pregnant but it was still early and I wasn't really telling anyone. So Tom was confused as to why I wasn't engaging with all the stunts, as I was game when we did them originally. So I told him I was growing a human. He was so cute about it and protected me - he almost went overboard on helping me. In the end I had to say, 'Tom. I'm fine, I can do stairs!'"

Charlize Theron, talking about her first movie, Children of the Corn III, says "I was an extra and I only had to run through a field and scream. I had to bring my own clothes. I was living from hand to mouth and had a brand new pair of Pumas and was really chuffed with myself and thought, 'I'm in a movie, I'll wear my new shoes,' and I got there and they just doused us in blood, which went all over my new sneakers. I was really upset about it, but not as upset as when I went to see the movie and they had dubbed my scream and I was like, 'Oh my god am I that bad?"

Seth MacFarlane, talking about his first non-animated screen kiss - with Charlize in their new movie A Million Ways to Die in the West, says "I was okay with it. I was a little afraid I would look a little goldfishy! But it was alright." With mock annoyance, Charlize interjects, "It was just 'alright.' Really?"

Talking about the success of Ted, Seth confirms Ted 2 is on the cards, "It will be happening in 2015. We are writing it as we speak," before performing Ted's Thunder Song to the delight of Graham and his audience.

Asked by Tom how many voices he can actually do, Seth says, "Just enough to avoid being myself," before indulging Graham by doing several voices from Family Guy and Liam Neeson's phone call from Taken in the voice of Kermit the Frog.

Coldplay performs A Sky Full of Stars, before Chris Martin and Jonny Buckland join Graham for a chat about the success of their new album. Asked if it's true it's #1 in 70 countries, Chris says, "I can tell you where we are not number one. Cambodia, Mongolia, The Bahamas and Burkina Faso, and it's number three in Kehjistan!"

Asked if they would be touring soon there was an emphatic 'No' from both members of the band.

Jonny, asked if he gets recognised, says "I was this morning but my first reaction is aggression, like, 'How do you know my name?'"

On whether other band members are recognised, Chris talks about the Grammys when Jonny and Will won an award, "They were back stage and a woman came up to them and asked if we were doing the catering!"
