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

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?

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.

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 find it's usually the bullies who are the most insecure.

I used to have all the Goosebumps books as a kid too.

I really liked the snake that breaks out of the cage in the beginning of the movie. I saw it in real life, and it was really cool. Really big and fat. The owls are cool as well, but you can't really pet them.
