Quentin Tarantino talks about strangling Diane Kruger; James McAvoy explains how he revealed all to his sister; Alan Davies says touring is a holiday; and Emeli Sandé explains her many Olympic appearances.

Quentin Tarantino, talking about his successful film career, and asked if he will retire after his 10th movie as has said, says, "Maybe, I don't know. I don't know what I will be doing next."

Asked if any actors have ever turned him down, he says, "Every once in a while it happens. I worked with Michael Madsen on Reservoir Dogs and I wanted him for Pulp Fiction, we really got along and I thought he was terrific so I actually wrote the Vincent Vega character for him. I worked on the scrip for seven months and he knew it was coming... Two weeks before I finish the script he takes another job can't do it!"

Asked if he then had to fight to get John Travolta he says, "Yes. No one wanted him. The film he had just done before Pulp Fiction was 'Look Who's Talking 3'".

Denying he tried to teach John Travolta to dance for the role, he says, "No, I didn't have to teach him to dance, I just wanted him to dance a particular way." Quentin then demonstrates Travolta and Uma Thurman's moves.

Talking about the lengths he goes to for realism in his movies, and asked if he really did strangled Diane Kruger in Inglorious Basterds, he says, "Yes. Whenever you see a close up of someone being strangled in a movie it always looks fake and I don't buy it. So I said to her, 'I want to do this, I'm going to be the hands and I am going to strangle you, I'm going to cut of your air and see the reaction on your face and then we'll cut - I'll do it only once.' She was okay with it. She trusted me and we got a really good thing - it was real."

James McAvoy talking about his new play, MacBeth, says "It's Scottish but there are no kilts, no shortbread, no Irn-bru, there may be whisky, there will be blood."

In true Tarantino-esque style Quentin directs Alan Davies and James in a scene from MacBeth.

Talking about his new movie Trance, James reveals, "We had a brilliant hypnotherapist working with us on the film but I couldn't be hypnotised. I think I might have been too keen to be and it got in the way of the whole process."

Recounting an embarrassing moment in his career, James reveals, "I was in Privates on Parade with Nigel Harman and we both came on naked and had to stand to attention for five minutes. It was all very interesting on stage but I thought I would look at the audience and realised my sister was there," indicating she was sitting right next to him level with his private parts.

Alan Davies talking about QI, and asked if he has retained everything he has learnt, says, "It all goes in one ear and out the other - I can't remember any of it."

And on touring for the first time since 1999, he says, "I fell out of love with it but I've really enjoyed touring again. I have two small children now so when I am at home it's quite full on and then when I'm touring it's like a day out - it's like being on holiday."

Emeli Sandé joins Graham for a chat. Describing last year as "Ace", she says, "It was amazing." And, on the success of her album, she says, "It's amazing, I never expected anything like that and what a year. I don't think I can top 2012."

Asked how she ended up in both the opening and closing ceremonies for the Olympics, she says, "I don't think the organisers knew I had been booked for both, I think it was a coincidence, but you just don't say 'no'."

Describing it as her favourite song, Emeli performs Clown live in the studio.
