People's instinct when they hear someone is madly obsessed with Star Wars or Harry Potter or something like that, they think that it's odd and not as cool as being a massive sports fan or film nerd. But I think it's amazing and something that should be celebrated and definitely not looked down on or misunderstood.

If young children boo me, that makes my day.

When it was offered [a role in The Flash] I just thought it sounded like the perfect thing that I would want to do. Then they announced it online the day after and I was terrified, because I hadn't read anything, I hadn't shot anything. What if I'm awful? What if they fire me on the first day? But what I discovered was a bunch of really happy actors who want to make the best show possible, because it's fun. Not for any other reason.

Knowledge will not be acquired without pains and application. It is troublesome and deep, digging for pure waters; but when once you come to the spring, they rise up and meet you.

Nothing's really changed since the Harry Potter films came along.

I used to be mad on the games, but I had to ban myself. I used to spend three dollars on games, [but] it adds up, so now I'm on the social side of things like Twitter and Instagram. I love my weather apps. I guess because all the Brits are obsessed with weather.

And to me, fame is not a positive thing. The idea of being famous is a lot better than the reality. It's fantastic when you go to premieres and people cheer you, but it's not real. And it's totally not my approach to get my name on a club door just because I can.
