When it comes to acting on green screen, it doesn't really make all that much of a difference to me because how you interact with your environment or characters is always dictated by your imagination. So when you're acting against a green screen, you have more of an opportunity to create your own world. So what was magical throughout this process was watching this movie come to life with the 3D.

There's a reason why Jules Verne chose the place where the glacier was, where we start to descend into the center of the earth. That area specifically has magical powers and people come to this place from all over the world. I actually think that's true of all Iceland. I think it's so special, apart from the water and air being so clean.

I try to show everybody Iceland all the time. My people are like, "Don't tell everybody the secret. It's so peaceful and beautiful here!" It's incredible; I go home and drive across country, and go to my mom's place and it's dark with the Northern Lights, and I like to sit in some hot springs.

It was a great joy for me to develop a strong female character in the spirit of an Icelandic woman. Icelandic women tend to be very strong and very independent, and I think that came in very handy.
