It's remarkable to see the advancements since the early days of [Harry] Potter with putting LEDs on everything, pointing sticks and measuring. Just archaic stuff. Now, it's like one guy with a laptop.

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 used to have some fish, some nice little carp, but they got too big for the tank. I don't have any pets now.

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.

It's shocking to say, but the cinema is quite a while away from me, and I haven't got a car yet.

I can't wait to see how Dan and I will look when we are older.

I like physics. I think it is the best science out of all three of them, because generally it's more useful. You learn about speed and velocity and time, and that's all clever stuff.
