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.

I want to take a few years out, maybe make a couple of more films or whatever.

It's such a pleasant experience [being a part of the DC Universe], though very nerve-wracking to come on to someone else's set, essentially. They've been there for two years, so for me to sort of walk on and to be expected to jump into it, it's not always that easy. But they made it incredibly welcoming and hospitable, so I'm very grateful for that.

The idea of being famous is a lot better than the reality.

You avoid the hype while you're working, you have to, but the premiere is the one night of the year where you can enjoy it.

Yeah, we held a junior carp tournament on the St. Lawrence River in New York last August. I hosted that along with a couple of other people.

People always tell me I'm nothing like my character. Well, hopefully not! He's a character who's very defined. He was purposefully written by Jo Rowling as very one-dimensional in the first few books, because you're supposed to hate him.
