Samantha: No matter what happens to you in your life, no matter what your circumstances are now or whenever, your soul fundamentally stays the same. I believe you make who you are before you get here, basically.
Samantha: I want to prove that you don't have to come from Oxford University or RADA--and you don't have to have parents that support you--to succeed.
Samantha: I think it's ridiculous that paedophiles get three months in prison when they rape a two year old. It's absolutely corrupt and this government has got to sort itself out, I'll tell you that now… It's mind boggling that somebody can get five years for having a bag of ecstasy in their own house but you can abuse kiddies and get two years.
Samantha: People seem to have been most affected by my performances when they've been a bit quirky, like Hattie in Sweet and Lowdown. People have fallen in love with her, with her sincerity, or for their own reasons. Hopefully these roles will come to me more now. It's hard to get things that are very well written.
Samantha: You have to listen to yourself and listen to how you feel when you do things. There are certain things in life that you shouldn't do and you know you're not suited to doing. If something makes you happy and you make other people happy, you should pursue that. I remember when I was 16 and I decided, that's it, this is my career now. So I got myself an agent. Fortunately, I started getting parts.
Samantha: (on acting) It started when I was seven or eight. In school, I had a brilliant teacher and it was the highlight of my day to write little plays with somebody or perform in front of the class. I had so much energy as a kid, as well, it was a way of keeping me occupied, my parents thought. It just went on from there; if you really enjoy something you can feel complete when you're doing it.
Samantha: Working in New York was just absolutely brilliant. I think I preferred being in America, because I felt everyone took it more seriously. In England, when you tell people you're an actor, they sort of think that it's a bit of a game it's not hard work. They don't realize that it's freakin' hard work. In America you've had a thriving movie industry for a long time now, and I think the general public realizes how [important] it is.
Samantha: Before, it used to be about my journey as an actor, just wanting to take different roles to test and challenge myself. I look at the world a bit differently now and I think about what I believe in and what messages I want to put out there.
Samantha: I don't tend to think too much about what I'm doing, if my emotional truth is there.
Samantha: I also have an imagination. I'm quite lucky to have a great one in that sense. What I tend to do with each role I'm not a method actor by any means but I really submerge myself in the emotional aspect of the role.
Samantha: I'd earn a million-squillion quid, and then my career would be over in two years. I'd die, mentally. I haven't got a problem with studios, or cash - just appalling parts for women.
Samantha: I was always a speaker in class, or someone that would beat up the bullies. I was confident because of the things I believed in.
Samantha: I don't mind working 15-hour days; I mind the drivers working 19-hour days. There's no unions anymore; Equity doesn't stand for f*** all. We're owned by these people. You feel lucky being an actress, because you get a really good pay-packet. But when you realise it's exploiting other people. It's a domino effect. I'll get into trouble for that. I always get into trouble!
Samantha: Without realizing it, you've actually become a ready-made family, like pot noodles - put the hot water in and it's there.
Samantha: My job is the same, whether they've got a hundred million or half a million. I go in and I play that character to the best of my ability.
Samantha: I thrive on constant stimulation artistically, whether it's listening to music, seeing art, or whatever. I try to inspire myself because the urban world and politics are quite draining.
Samantha: I've got a lot of stairs in my house! I'm on the sixth floor. I should be fit and have a really nice ass, but I don't.
Samantha: Some directors cast you because they trust you to do the performance - but then they forget to direct you
Samantha: People need to know that you're versatile, otherwise you don't get the opportunities.
Samantha: I have to have the director be my guide - I have to have that relationship with the director or else I go bonkers.
Samantha: You've got all these books on self help, getting to know yourself, doing the right thing, eating the so-called right foods, even down to what books you have on your shelves. People are encouraged to look to themselves first as opposed to being a part of society.
Samantha: To be honest with you, a lot of directors can be very lazy.
Samantha: We're all living blinkered lives, and we're not seeing what's going on and looking to change it. I'm not saying that everyone has to make a political statement, but we need to be more aware of what's happening and why.
Samantha: (on choosing the right films to act in) You gotta do stuff that inspires you, otherwise your life's so boring, and you go home and feel a fraud. With scripts that come through the door, as a woman, you go, "Bollocks, bollocks, bollocks, bollocks." As a kid, seeing [Ken Loach's] Kes and then Ladybird, Ladybird changed my life. That sounds wanky, but if you're going to be an actress, to me, I want to be part of a team of people that I don't only respect but I feel are trying to make a difference. If we can just change one person's point-of-view...
Samantha: Acting and music are self indulgent professions and they are a luxury unless you love what you do. I have a love/hate relationship with what I do. I think, 'Where's the relevance of this? I'm not a doctor, I'm not an aid worker.' But then I think you only have one life and I am a vessel for stories to be told.
Samantha: In films, it's just that one minute you're strong, then you're told you're difficult. The minute you say, 'No, I won't take my top off' or 'No, I won't work overtime', you're bloody difficult.
Samantha: With publicity, you have to retain a level of privacy. For me, work and my life shouldn't be one and the same.
Samantha: Woody Allen makes Woody Allen comedies and they are all about him. Steven Spielberg likes to tell someone else's story and it is not only about him. Fine direction such as Spielberg's is rare. You have to be very confident to direct actors. Too many directors merely know where to point the camera.
Samantha: My foster mother died and I did not have a relationship with my real parents. I know who they are. It's not upsetting; it's just the way it is. You cannot change things. My childhood isn't like an albatross around my neck.
Samantha: (how she got the acting bug) It started when I was seven or eight. In school I had a brilliant teacher and it was the highlight of my day to write little plays with somebody or perform in front of the class. I had so much energy as a kid, as well, it was a way of keeping me occupied, my parents thought. It just went on from there; if you really enjoy something you can feel complete when you're doing it.
Samantha: (on her engagement to Harry Holm) We're over the moon. We're very much in love and looking forward to spending the rest of our lives together.
