Chris Hemsworth says people mistake him for Liam, Jessica Chastain reveals she has pretended to be Bryce Dallas Howard, Kirsten Dunst talks about Tom Cruise's generosity, Stephen Mangan says acting with his wife was weird and Raleigh Ritchie performs live in the studio.

Chris Hemsworth, talking about his new Huntsman movie and asked what it was like working with Jessica Chastain, Emily Blunt and Charlize Theron rather than a male cast, jokes, "It was great - there was a lot less testosterone!" Adding, "It was a different chemistry but a lot of fun with three incredibly talented and intimidating women - I loved it!"

Asked if he is ever mistaken for his brother Liam, he said, "Now I have a beard it happens more. The first time was at the Star Trek premiere. It was the first big thing I had done and I remember thinking, 'Wow, this is the beginning of my career,' and a bunch of people were there and they are like, 'Chris, Chris, Chris,' and then ran straight passed me to Liam. I thought he was going to correct them but just winked at me and started signing autographs! That was my first little brush with fame!"

Jessica Chastain, revealing she has been mistaken for Bryce Dallas Howard, says, "At the beginning of my career I was doing a play off, off, off Broadway and was on the subway when a group of college kids sitting opposite were smiling and pointing and they told me I was a brilliant actress. I was like, 'Thank you so much, I can't believe you recognised me,' and I had the feeling of 'this is what it is going to me like.' Then one of them said, 'I can't believe you managed to play blind in The Village.' I didn't want to embarrass them or myself so pretended to be her!"

Talking about April Fools' day pranks, she says, "I was terrible when I was a little kid and bought these little makeup blood capsules, put them in my mouth and pretended to walk into a door. Blood would be gushing from my face and of course my mother would be completely panicked and freaked out... and now I am an actress!"

Kirsten Dunst, continuing the theme, says, "Every year I would tell my mum I was pregnant and depending on my age she was either really excited or very supportive. She falls for it every year."

Talking about appearing in An Interview with a Vampire at such a young age, she says, "It was important that I went to proper school between films - it was a good balance to go back to school and to your friends."

Revealing she is still in contact with Tom Cruise, her co-star in the film, she says, "He sends me a cake every Christmas. We are very excited to receive 'The Cruise Cake.' He has kept it going for a really long time, which is impressive. I've never given any one a gift for that length of time except for my parents."

Stephen Mangan, talking about his one-week old son says, "Being here is a holiday for me. The baby wasn't planned and if he had been a girl we were going to call her Cilla. Surprise! Surprise! We really need to work out how it happened!" Asked if he is enjoying a third baby more than the first two, he says, "You can because you are not afraid you are going to break it, you know they are okay and it is an absolute joy."

Asked about acting with his wife in his new series Houdini and Doyle, he says, "It was really bizarre and very peculiar to be kissing her with lots of hairy men looking on. It was weird, but nice to see her to catch up on the family!"

Raleigh Ritchie performs Stronger Than Ever live in the studio, before joining Graham for a chat.
