Rose: I'm excited about going back. I love the regularity of a series, I think having regular work has probably given me more confidence and security. I tend to spiral out of control if I'm not working. I get panicked and don't know what to do with myself.
Rose: I loved performing; I was always trying to impress my siblings by being a clown. I think that came from being the runt of the litter.
Rose: Television is a different skill; it's more like you are a character in a novel. You need to allow the audience in more and to create a private life for your character so that you are fully rounded and not just like a cut-out, so the audience invests a bit more in you and wants to come back.
(On what people find surprising about her)
Rose: Usually that I'm much more light-hearted than they think I am. I often do very serious roles, but really I am a big clown.
(On her and her husband enjoying New York City)
Rose: I'm in love with the city. You can impress an Australian with a city, but you can't impress them with a beach. Brendan writes and he really enjoys it in New York.
Rose: You know, I'm Australian, so I'm not too flashy or glitzy... I've stopped dressing for other people. If I think I look good, that's the most important thing.
Rose: I see myself more as a character actress than a celebrity.
Rose: The worst was the time I spent in Los Angeles, which runs on bullshit and cliches. But then, it's really easy to diss the place. The physical environment of LA is really beautiful. It's actually kinda fun, too, if you're working. It's just not really fun if you're not working and you don't know anybody.
Rose: I'm starting to know how the world works a bit, and I'm learning more and more that the only thing that matters is what happens between 'action' and 'cut'. I'm allowing myself to be a bit more selfish, for want of a better word, just that it's OK to focus and that I don't have to be nice to everybody.
Rose: I guess you can get to a level where you choose. I guess when you reach that point maybe you start making decisions about whether you want to be a leading man or woman. I'm not at that point at all. Where I am now, you're very much at everybody else's mercy. You have no control over your career in a lot of ways. It's just important to know what your own goals are, because that's empowering.
(About her most dreadful crush)
Rose: I used to drive, pretty pathetically, I'd just drive by their house all the time and they didn't know who I was. I'd just drive by the house all the time. I once knocked on the window and I thought, 'What am I doing? What am I going to say if they come to the door and don't know who I am?'
Rose: TV is very much a producer and writer or creator-driven machine in the States. And I'm the kind of actor that needs to be pushed and have someone on my case a little bit, so I suffer from that. I'm always prepared, I always do my research and have my perspective, but I think I personally flourish better when I have someone moulding me a little bit more.
Rose: I think it's important to keep an element of fear about yourself because it makes you appreciate the jobs.
(About her role in "Star Wars: Episode II - Attack Of The Clones")
Rose: That was easy, I just stood by Natalie Portman looking very serious.
(About being labelled the next big thing)
Rose: I don't take it, seriously. Because I'm the one living my life. I mean, I've got this tiny part in this big Brad Pitt movie, and everyone here thinks I'm playing Sally to Brad Pitt's Harry. I'm not, and I'm constantly having to say that.
