You do that stupid thing at 12 years old when you say something and it kind of sticks with you for the rest of your life. So, I believe I said I wanted to be a fishery manager. In hindsight, I think acting could be a better route.

One thing that people keep on saying to me is that the wealth and the fame must have made up for missing out on my childhood. But the idea of money - putting a price on your childhood - is ridiculous. You will never get those years back and you can't put a price on them.

I'd love to be in Paul McCartney's shoes for a day. I'd love to pick up a guitar and write songs like he does. Or to experience what it might have been like to be a Beatle for a day.

I already love the idea that Barry has a colleague. It seems like a love/hate thing between my character and his already. They work together, so they clearly have some tolerance for each other, but they're just ruffling each other up the wrong way, constantly. I don't know whether that will lead to him being suspicious of Barry's identity or whether he'll have some clash with The Flash.

[Julian Albert] is a CSI investigator; a forensic expert with similar skills to Barry, which gives them a different relationship to, I think, anyone else that he works with, because they're sort of treading on each other's toes in their field of expertise.

I think it's pretty crazy to say you've been typecast at the age of 20 before you've even really started getting going.

I'm not one generally to do that stuff anyway, and they didn't even ask me whether I'd seen the show [The Flash]. They didn't tell me anything about what I was going to play, they just inferred that there was going to be a lot of meat to sink my teeth into.
