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."

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.

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."

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."

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!"

I'm incredibly grateful for Sophie Barthes, I'll always be incredibly grateful for her being generous enough to believe in what I thought. And it was just lucky that I met the right person.

I can think of a handful of auditions where the director has literally said, "That is the opposite of what I think." But it's really good to be honest and have that dialogue. I don't think you should be criticized though.
