The Barack Obama Administration has prosecuted more whistleblowers than all previous administrations combined. That's a staggering record. And it comes from a president who said that he's going to have one of the most transparent administrations ever.

In a busy world, even as information is moving so rapidly, we have to learn who to trust in that regard even as we ourselves have to become more critical of the people who we want to trust. It's a weird situation.

Many people, including myself, thought of Jobs as an inventor, an Edison-like figure, but he wasn't. I did a documentary on James Brown recently; and, oddly, I found a lot in common between Jobs and Brown. Jobs was also a fantastic performer, put on an extraordinary live show at his product launches, but he could also be ruthless, cruel and totally self-aggrandizing. And just as Brown surrounded himself with the very best musicians, Jobs understood the importance of hiring the absolutely most talented people and knew how crucial they were to the success of what he was trying to do.

What's great about the Sundance Film Festival is the festival takes over that town as it's intended to do. But, it's very focused on a lot of other filmmakers and distributors so it almost feels like, while they're a lot of so-called civilians there, it's an opportunity that you have to see, to show your stuff to the other folks, your peers really, and to get that reaction.
