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.

I like to fish. Fishing is always a way of relaxing.

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.

There's a real feel-good warmth to the show [The Flash]. It feels like you're watching, for lack of a better analogy, Friends mixed with Spider-Man or Batman.

I took the original stuff that I read as standalone [in The Flash]. I didn't have anything to refer to, so to me it was all new. It's delightfully simple, the show, but it has many moving parts. It certainly makes you pay attention.

As soon as you see 'Dame' in front of someone's name, you get nervous, but Dame Maggie Smith is the most wonderfully gentle woman I have ever met. She never had a bad word to say.
