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.

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'd like to own my own garage and my own fishery. I'd also like to be a professional fisherman. But I'll take whatever happens.

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.

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.

I'm a keen musician. Me and my mates have a great times jamming and recording stuff. We have a great band behind us and have turned my nursery-rhyme songs into quite credible pieces of music.

There's something very intoxicating about playing someone so volatile and someone who can lose his temper at any second.
