Rachel and Bradley - you have to share a screen kiss. What was that like?
Bradley: She had to beg me to do it!
Rachel: I didn't think we would be embarrassed because we know each other so well, but we were.
Bradley: There were people all around us, just watching.
Rachel: I would give him 6/10.
What's your favourite scene?
Rachel: We do a jail scene to Don't Stop Movin'. It reminded me of a big musical number. Everything felt that bit bigger and it was really exciting.
Gareth Gates makes a guest appearance in the film - what was it like working with him?
Bradley: I remember him saying he was kind of nervous, but it didn't show.
Hannah: He was brilliant.
How do you feel about S Club's image?
Jon: We never came out and said 'We are this really squeaky clean band and we are a great role model for your children'. That's what people started saying about us - it's a great responsibility to have, but it's not on my mind 24/7.
How have you changed since you got together?
Bradley: We were all pretty young when we first started. Our opinions have changed quite a lot. When I was 16, I thought 'I'm going to be on TV, I'm going to get loads of girls'. Now I'm more focused. I take it seriously.
Do you ever fall out?
Bradley: The hardest time we have been through is when we have been filming constantly for three months. We get a bit tired and there are arguments, but once we have had a little break and we are refreshed, we always feel better.
How do you cope with the attention from fans?
Hannah: It's only when we're together as a band that people chase us!
Rachel: A lot of people just want to say 'hi'. They just come and have a chat.
Bradley: It's not that hard to take out five or 10 minutes of your day to sign autographs and stuff. I end up having tea and coffee with people!
