Growing up the son of a director has made me very aware of the various turns that a directing career can take. Sometimes your films turn out exactly as you want. Sometimes they don't. I spent a lot of my childhood on sets. I think as a joke, my father gave me a line of dialogue in each of his films during the worst moments of my puberty.

Growing up sucks, doesn't it? I understand why people wouldn't want to get old - but it'd be one thing if we became a culture obsessed with eating right, doing yoga, going to therapy and becoming at one with ourselves. That be great. But we don't do that. We seem to be obsessed with all the wrong ways to stay young.

Alien' asked ground-breaking questions about eco-politics and female empowerment. 'The Matrix' delved deeper into the concept of perception versus reality than perhaps any other film I know. But for some reason, we tend not to remember the significance of their writing.

I've always been about how will digital be transforming established businesses, and that's what I've done.

It feels wistful to imagine a time when people didn't go about their daily routine with the assumption that at any moment another massive media technology will be dumped on us by some geek in California.
