My first professional audition - god, I've never told anybody about this - was for a test commercial, I think it was for Xbox. It involved me getting kidnapped by a granny who wanted to play the Xbox. It was very weird and I definitely had no idea what I was doing. I actually got the gig. It wasn't a commercial; it was what directors did when they wanted to show the company what they would do with a commercial.

My grandfather told me that I should have a series of headshots, one with a tennis racket, one dressed as a naval officer, and one dressed as a cheeky chappie. He said, "If you have those headshots, the world is your oyster."

I wasn't particularly prolific at sport, and I could get by at school, but I wasn't going to win any prizes. Suddenly people were slapping me on the back and saying that I was funny and talented. So I just knew that it felt good to be appreciated, basically. Whenever I got an opportunity to do some acting I did a little bit more.

I suppose it's really satisfying to play someone with secrets. It's really satisfying to decide how and when those things are going to start being revealed, and how subtle to be.

I think you have moments of doubt and moments where it feels really hard. You certainly have to be patient, and I'm a very impatient person. It's been like when Yoda teaches Luke to be a Jedi; the things that I do professionally have taught me new levels of patience.

There was still an element in acting, certainly for my dad, of like, "This is lunacy." But then once my parents could tell that I was serious, it was like, "Okay then."

There's something great about being a really young actor because you don't have a chance to be nervous. You don't know anything yet. Whereas one of the big challenges as you go through - I've been doing acting professionally for 10 years now - is to not let all the things that you know hold you back and make you more nervous. Once you've had a few people tell you that they don't like your ideas, that voice in your head can creep in that says, "Don't tell them what you think."
