I think it's radical to censor information because the government asks you to. That's radical.

From a personal perspective, because I'm on a watchlist and went through years of trying to find out why, of having the government refuse to confirm or deny the very existence of such a list, it's so meaningful to have its existence brought into the open so that the public knows there is a watchlist, and so that the courts can now address the legality of it. I mean, the person who revealed this has done a huge public service and I'm personally thankful.

I was in correspondence with an anonymous source for about five months and in the process of developing a dialogue you build ideas, of course, about who that person might be. My idea was that he was in his late forties, early fifties. I figured he must be Internet generation because he was super tech-savvy, but I thought that, given the level of access and information he was able to discuss, he had to be older.

We're definitely in an era where the government wants to keep more secrets and it wants to come after anyone who's exposing those secrets and in many cases exposing government illegality. They're coming after the journalists and they're coming after the whistleblowers. It's not a good sign if the government is expending much energy trying to find out who journalists are talking to.

I think one of the most shocking things is how little our elected officials knew about what the NSA was doing. Congress is learning from the reporting and that's staggering. Snowden and [former NSA employee] William Binney, who's also in the film as a whistleblower from a different generation, are technical people who understand the dangers.

People are starting to understand that the devices we carry with us reveal our location, who we're talking to, and all kinds of other information.

Snowden has presented us with choices on how we want to move forward into the future. We're at a crossroads and we still don't quite know which path we're going to take. Without Snowden, just about everyone would still be in the dark about the amount of information the government is collecting. I think that Snowden has changed consciousness about the dangers of surveillance.
