If it was a biopic about Glenn Greenwald, I would have immersed myself more fully in his personal life and gotten to know him as much as I could, but because it was much more about his relationship to this particular situation, to The Guardian, to Laura Poitras, and to Ewen MacAskill, and Edward Snowden, I was able to really learn a lot about him from reading his book and reading his many articles and accounts of that time.

I would say auditioning was my real training ground. The technical aspects - like hitting marks and pacing yourself and preparing and dealing with the downtime - the first recurring role I had on 24 was probably the way I learned that stuff.

I remember standing outside of the dorm by the little terrace. I was going to do this job that I wasn't 100 percent certain of, which ended up being much more fun than I expected [in So Notorious].

I feel like that [the role in Star Trek] is a prime example of, yeah, I got that role and it was awesome, because it changed a lot for me professionally, but then creatively, it became a whole other thing, with J.J. [Abrams] and Chris [Pine] and the people I got to know. Now I just feel like it's our jobs to be open and to keep moving stuff forward. I don't know what that means. This is the first time in a long time that I have no idea what's happening next. As scary as that is, and as anxiety-provoking as that can still be, it's also really exciting.

I think I integrated that over the first couple of years that I was out of school, mostly in auditions, to be honest.

I went away to this summer program after my junior year of high school. They used to have this thing called the Governor's School, and they had it for different disciplines - science, math, performing arts. I auditioned and I got accepted, and it was an eight-week program away from home. I went for acting. I was 15, and I turned 16 while I was there, so that was a seminal moment for me. It made me realize the life of it, the discipline of it, and the joy of that discipline, where it was all we did.

The razor-sharp line of division that exists between political ideologies in our own country in the United States, I think it's clear that these movements are forming - and one is more forward thinking and more embracing and more inclusive. The other is less tolerant and more judgemental and more fear-driven and fear-based. I think, you know, over the next generation, we're going to see which way we turn as a civilisation.
