I made films with my brothers and my cousins and if any of the films ever come to fruition my career will be in ruins because the acting, writing, and directing is so unbelievably, heinously bad. We once screened one for my grandfather, this film that we had painstakingly made over a couple of days when we were all 10 years old, and he sat there and he said, "This is the worst film I've ever seen." No sympathy whatsoever.

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.

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.

If you want to have the right to have that conversation with your agent - "I know you sent it to me, I know you like it, but I just really think it's terrible" - you need to have the full details about script. You don't want to be in that situation where your agent says, "What about after the first 20 pages where it turns into a psychedelic musical?" And you're like "What? I thought it was an action-rom!"

Once you get an agent you're given an opportunity to try a little bit more. It's a really long ladder.

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.
