It's such a cool group of people that it [being a part of the DC Universe] feels like, for lack of a better analogy, being back on something like [Harry] Potter. We're working with a really tight, talented family.

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.

It's like in politics: You can have great intentions for the world, but if you're not a good speaker and if you're not the sort of person that people can intimately link with, then it makes it very easy to say, "Well, they're not a nice person."

One of my first things I was fascinated with when I got on set was how does Grant do all this Flash stuff? it looks so good as the end product, but how does the special effects team work? How does the visual effects team work?

You see another side of Draco when he's with his dad. When Draco is with his dad, he doesn't say anything. He keeps his mouth shut. He's sort of bullied by his dad, so he acts very different.

I like a funny girl. Smart. Talented. I like someone who is good at music - that always intrigues me.

I don't like to label films with a genre.
