When the financial crisis arrived, it seemed to me that this was something I had to make a movie about.

When the U.S. government is serious about doing something that's complicated and difficult, it can do it.

WikiLeaks combines several of my prior interests in technology, policy questions, and journalism.

It is no exaggeration to say that since the 1980s, much of the global financial sector has become criminalised, creating an industry culture that tolerates or even encourages systematic fraud. The behaviour that caused the mortgage bubble and financial crisis of 2008 was a natural outcome and continuation of this pattern, rather than some kind of economic accident.

If allowed to continue, this process will turn the United States into a declining, unfair society with an impoverished, angry, uneducated population under the control of a small, ultrawealthy elite. Such a society would be not only immoral but also eventually unstable, dangerously ripe for religious and political extremism.

I thought I should try something relatively inexpensive, relatively contained, relatively small. I started working on a feature, a film I'd still like to make: a very talky film of people and ideas about our contemporary state with regard to relationships, marriage, sex, and romance. I started trying to educate myself about filmmaking.

The real challenge is figuring out how the United States can regain control of its future from its new oligarchy and restore its position as a prosperous, fair, well-educated nation. For if we don't, the current pattern of great concentration of wealth and power will worsen, and we may face the steady immiseration of most of the American population.
