Creativity is the ability to introduce order into the randomness of nature.
What people fear most about tragedy is its randomness - a taxi cab jumps the curb and hits a pedestrian a gun misfires and kills a bystander. Better to have some rational cause and effect between incident and injury. And if cause and effect aren't possible better that there at least be some reward for all the suffering.
And of course I've got kids of my own now and they love me being in the Harry Potter films. I'm now part of a phenomenon. You become incredibly cool to your kids and you get a young fan base. So you became the cool dad at school. You're suddenly hip.
