Ryan Kwanten: Obviously you've got to have the talent but what I think is so important in this town [Hollywood] as well is to have resilience and tenacity, you've got to be able to deal with rejection, more so than any other job. Even in a good year you're still getting rejected more than 90 per cent of the time.
Ryan Kwanten: To be a man means more than having muscles; there's so much more to being a stand-up guy. I always loved that Ralph Waldo Emerson quote: 'What lies behind us and what lies before us is small matter compared to what lies within us.'
Ryan Kwanten: I'm confident with who I am. I know what I'm capable of, and without sounding like an egomaniac, I have no problems quashing anyone's expectations. Whenever they say I can't do something, it just inspires me more to do it. If somebody tells me that's my pigeonhole, I guarantee you I'll break out of that.
Ryan Kwanten: I always grew up with physical activity, so now it's just a part of who I am. I do a little something every day. Even when I'm working, I'll go home and run on the soft sand at two in the morning. No matter the time, even if I have to wake up at four, I do whatever [exercise] I can. If I don't then I'm not me.
Ryan Kwanten: (on his hidden talents) I'm undefeated in Scrabble. I can figure out an opponent's strategy and mold mine to offset theirs. I play a couple times a week, and I'll often play a game on my bed by myself against myself, which I realize sounds completely mad.
Ryan Kwanten: Australian women tend to tell it like it is-even if it's the brutal, honest truth. I think American women usually break it to you a little easier. There's a softer side to them.
Ryan Kwanten: (in a 2008 interview) As much as I come from a country that's very liberal and open-minded, in regard to one's body, I feel like I've got myself in a position in my career where I should be careful when I'm being naked, as any actor should be. I think it's important that it's a relevant story point, and not just nudity for gratuity's sake.
Ryan Kwanten: (about who he wants to be for one day) Ewan McGregor. To me he just means cool.
Ryan Kwanten: (about what he looks for in a girl) I'm not fussy. All of my girlfriends have been really different, personality-wise and what they looked like.
Ryan Kwanten: I think it's important to get your sweat on and to not just limit yourself to one particular sport. To do nothing but lift weights to me would be a quick death. Life has too many great things to offer in terms of physical exertion. I think you always need a sense of clarity, whether you get it through meditation or going for a hike, when it comes to bettering your life. It may not work for everybody, but it does for me.
Ryan Kwanten: (about his favorite music) I love rock. My favourite artist is an Australian guy called Johnny Diesel, and my fave overseas band has always been The Beatles - you can't top them.
Ryan Kwanten: (about his starsign) I'm a typical Sagittarian, I like having things my own way and I'm a really active type.
Ryan Kwanten: (about how his acting career started) When I was 15 my brother went along to an agency audition and I came with him on my way to going swimming. The woman there asked me if I wanted to audition as well and I said, 'No way, I can't act!' But I thought I'd have a go anyway and they ended up signing me and not my brother!
