As you get older, it's important to have goals. When you're a kid you have them, but other people can set them for you, such as your parents, your school... so, as you get older it's nice to have your own goals, which don't have to do with being more famous, or being in bigger movies, or making more money. Those things kind of corrupt your soul.
I like the old school heavy metal bands like AC/DC and Aeromith. I like that type of music. As the director, I tried to influence the type of music the bands in the movie would play.
When I was a kid, I was like everyone else: afraid of getting nuked. We had drills in school - Sweden was very close to the Soviet Union. There was definitely a lot of tension.
