There are instances where, in my mid to late 20s, I very often found myself going for roles that they didn't want to cast me in, because I'd done good work, but in a producer's eyes, I wasn't high enough status. So I lost out.

There are actors who do various different shades of a similar character, which is fine. But I prefer the Cillian Murphy school of doing something that takes you so far outside yourself that it's an incredible challenge and adventure.

Who doesn't change through their 20s? I changed probably more than the average person who lives in one place and has a job. But everybody changes significantly in maturity, we'd like to think, from 20 to 30.
