Sophia: I feel very much that I'm a marathon runner in this profession. I've never been a sprinter. There have always been people who've darted ahead of me the minute they've left the starting line.
Sophia: (on choices) I've always said that I'd rather work for nice people for no money than get paid millions to work with idiots. People think and say that I'm really interesting because I've done studio pictures and then art house films, but I've never made any conscious choices. I always base my choices on the material that's in front of me, as well as who's in it, who's directing it and is the writing any good? Those are the three main things. I don't care how much money is in it, who's producing it, who's whatever. So whether it's TV, film or independent studios, that's the criteria. It's also instinctive because when I read a script and the character they're asking me to look at, if I can hear the voice in my head, that's when I know. Sometimes you read stuff that's obviously good but you can't see yourself doing it.
Sophia (on turning down university for acting): I have no regrets, because I completely fell in love with this industry as soon as I walked on to my first job. And I was thinking, well, I can either go and sit in a classroom and study Jane Austen or Harold Pinter plays, or I can make Mansfield Park and work with Harold Pinter, and be paid to do it, and be in the cinema. So no regrets.
Sophia: (on the time before her breakthrough) Keira and I played sisters in Oliver Twist, in 1999, and after that neither of us could get a job. We were like, "Why are we unemployed? Are we mingers?" We even thought about writing something for ourselves.
Sophia (on her style): I'm not so much a tomboy, but I always feel like I'm a man in drag. When I was a kid I never had a doll or wanted a Barbie. I used to like playing soldiers and climbing trees.
Sophia (on rebelling): I was always the good girl at school. Some of my friends were getting pregnant and into drugs, but the most I did was smoke a packet of 10 Marlboros.
Sophia (on dreams): I read once that the two worst things that can happen in your life are: achieving your dreams, and not achieving your dreams. I'm living living my dream and I'm scared. I think that it can't go on like this because it's too perfect. I can't plan my life because at this stage in my career I'm not in control of it. I believe in fate; after all, it happened to me.
Sophia: People ask me about it all the time. But my recollection of growing up was that being a vicar was just something my dad did for a living and religion was not rammed down our throats at all. My dad is philosophical about what I do, and both my parents are very supportive. Even when things get a bit near the knuckle. They accept that I'm acting.
Sophia: (on her father being a vicar) It's not because I'm not religious, but I wouldn't want to be in a classroom where one of my parents was the teacher. Anyway, it's odd going into church having had a big bust-up with your dad in the morning and he's saying "I forgive you for all your sins" - and you're going, "Yeah right, Dad."
Sophia: (on the prospects of paparazzi following her) Quite frankly, I'm so boring in my real life that the only thing that's cool is what I do for a living. That's the rock 'n' roll bit of me. My daily existence would make them so bored.
Sophia (On her resemblance to Kate Winslet...):
I have met her once at the BAFTA awards, I am sure she doesn't remember me. But I think it would be perfect casting to hire me, if someone ever needs an actress to play her young sister. I am incredibly flattered by the comparison, because I think she's is stunning and talented and a really nice girl.
Sophia: (on acting) I'm quite shy naturally so acting is good for me because it's really forced me to face my biggest fears and come out of my shell.
Sophia (on what she does during periods of unemployment?): A lot of soul searching. It's really hard and that's the down side. It does happen to a lot--even the greats have a lot of time off work. It's very rare to job hop. I do think it's important to take time off between to recharge your batteries and to go back to the real world but there's nothing worse than being forced. The thing is, if you're a musician, at least you can pick up your violin for example and play music but with this craft you have to wait to be asked to act and that can be frustrating at times and also dealing with rejection. I didn't go to university but I do feel like I have an M.A. in coping with rejection, I really do. You get so strong about it.
Sophia (on her idea of romance): Sense of humour is the number one thing for me. Somebody that can make me laugh, somebody who cares really and isn't too self centered and somebody that has the same kind of ideas about how they want to live their life and same aspirations in terms of family. All of this stuff is great and it's fabulous but really coming home at the end of the day is what's important. I think it's better to come home to something nice than to leave every morning going to work, thinking "Thank God I'm out of there," so.
Sophia (on Keira Knightly): I am so impressed by her. We played sisters actually but we didn't actually work together. Keira took over from another girl on Oliver Twist, that was for ITV, so we've known each other for years and years. She's great because she hasn't changed an inch and she's really down to earth and has such a good attitude about it all. She takes it in stride and she's about four or five years younger than I am. For a young woman of her age, I think she has handled herself incredibly well. I think if the success that's happened to her happened to me at her age I'd probably be in The Priory by now. I'm just so delighted for her. She always says, 'Whatever they ask you to do just do it, be gracious, be nice," and it's the best way really. And don't talk about your private life.
Sophia (how she got interested in acting): Basically there was a really gorgeous, or so I thought, drama teacher called Kevin Broadway who'd I'd seen walking around the corridors - I kid you not. Truth be told I only did drama because I quite wanted to be taught by Mr. Broadway. We put on a play as part of our GCSE exam called Teachers, by John Godber. It was only on for two nights and after the first showing a gentleman came up to me, Julian Fellowes. He wrote the screenplay for Gosford Park and since won an Oscar. He was writing and producing a costume drama for the BBC, The Prince And The Pauper and invited me to come and audition. I did, and I got the job. The minute that I walked onto the set I just knew - I thought, "Oh I like this," and I just completely fell in love with it really and knew there was no turning back after that. School became so boring as soon as I started working really.
Sophia: I used to watch Doctor Who when I was a kid so to be in it is such a privilege. It's a job you can't say no to. It's a bit like being called to jury service, it's not cool to say no.
Sophia: I hope that other women will think it's refreshing to see a normal-sized woman on screen.
Sophia: Sense of humour is the number one thing in a man because I need somebody who can make me laugh. I need someone with the same ideas and aspirations as me, because of all that stuff is fabulous, but coming home at the end of the day is what's important.
Sophia: There have been occasions when my agent has said I didn't get a job because I was too hefty. But the heaviest I've ever been is a size 10! I find that rather sad and don't want to work with people with that attitude. I honestly don't know where this skinny stuff began. Men don't like it either.
Sophia: I was trying on some jeans and thinking, Great, I can get into a size 27. But this painfully thin woman in the changing room was complaining, Oh, the 22 is way too big!
Sophia: My biggest ambition is to have a family. To have a baby is one of the most amazing things a woman can do. Not that I want to do it until I'm ready. There's so much I want to do first.
Sophia: I noticed when I turned 25 that my metabolism slowed down, which is painful as I'm a major foodie. Now for example, if I'm craving pasta I'll eat it at lunchtime instead of in the evening. It's just a question of having discipline and understanding nutrition.
Sophia: I love designers who really embrace women's curves. My favourites are Agnès B, Alberta Ferretti, Armani and Stella McCartney.
Sophia: I think you have to make sure you scrub up well when you go out. Otherwise, I'm a bit of a slob at home. I am make-up free.
Sophia: If there is going to be nudity in a film, I would rather do it myself than use my body double. If they use one, they can go and do a day's shooting, you don't know what they're doing and people still think it's you.
Sophia: It was just usually really cold and really wet. The funniest scene was where we drag James into the hut. We referred to that scene as the Franco sandwich, me and Bronagh. When she drops down naked and said the line, 'Aah, I haven't been naked with a man for 15 years!' we always used to find that so funny. You know when something kinda gets you and you just can't stop? I'd see him shaking and I'd start laughing... it took about 69 takes to do.
Sophia: I get a lot of fan mail from kids, it's brilliant. They're so much more honest with their letters.
Sophia: For me it's my favourite part of what I do for a living, the challenge of taking on a new accent. Since I was a very young kid my brother and I used to mimic people, I love it. I worked with a brilliant dialect coach on Tristan + Isolde and he taught James Franco to do English and me to do Irish. Also being submerged in Ireland when we were shooting makes it so much easier when you're hearing it constantly.
Sophia: The scene where James [Franco] and I push the boat into the water... it took, like, two days, and I didn't have anything under my costume because it was so kinda flimsy. We'd do one take and then we'd go and sit on the beach and James and I were like drowned rats sitting there in wet clothes, being cold. My brain just froze, I couldn't think. James' teeth were chattering uncontrollably, he just couldn't stop it. It was properly rugged. I think working in the elements like that, it brings the energy. You can see it's cold.
Sophia: We were doing Doctor Who and Steven Moffat the writer brought his son along, who's six. He came on the day that my character, Madame Du Pompadour, who's the soulmate of The Doctor, has a little bit of a snog. Steven's son Joseph was obviously a big Doctor Who fan but also a massive Thunderbirds fan. Part of the reason I got the job was because Steven was forced to watch Thunderbirds about 80 million times, so for Joseph to see Doctor Who and Lady P getting it on... I mean, this little kid was bowled over.
Sophia: When my agent called and said I'd been offered Doctor Who I thought "Brilliant, I'm going to meet the Daleks." It turned out I was going to be in a corset in Versailles as Madame Du Pompadour. She is the mistress of Louis XIV and in Doctor Who terms has known The Doctor since she was a very young girl and he's visited her through the course of her life.
