I had this alter ego where I would go to the theater with mom. I wasn't embarrassed by it; it was separate for me.

I started coming to L.A. as often as I could, for three months on and three months off, because immigration kicks you out after 90 days.

I was always trying to perform, but never with some dream to be on the stage. The stage was wherever I was standing at the time. I was lucky that the department of education in Sydney had a program where you could try out for these ensembles - kind of like extra-curricular sports, but for little drama kids. I got into that system, and it took me right through high school.

There are roles out there I want to play that I don't know if I'll ever get the chance to. But I'm not going to waste time waiting for those phone calls, passing up the chance to do these sorts of things. I'm more likely to go see a smaller, darker indie film, like Felony for instance, than I am to see an Avengers or perhaps even a Terminator.

I went to the Avengers: Age of Ultron and I'm like, "These guys are Olympians now." There's no place for a Walter Matthau in a movie anymore.

I love that about filmmaking - seeing final product and getting to see everyone else that you don't necessarily engage with on set every day and getting them to showcase their talents. Whether it's effects, music, the edit, the rhythm of a film is driven by that, so it's cool to see it come together. It's great to be standing in front of something you're genuinely proud of.

Some people have this really clear memory of making that decision, and I don't. My earliest memories of being involved with drama or acting were in elementary school. My sister and I got dropped off at an after-school improvisation class, a time-killer for kids while parents were doing the groceries. I'm 6 years old, and I remember running amok and playing these games.
