Are you giving him flak for misspelling Ellsberg? Because otherwise Daniel Ellsberg was the keynote speaker at HOPE X (which the keynote was right before Snowden's talk), and was the one asking the questions to Snowden.
Instead, I really suggest learning more about Ellsberg, it's definitely worth, in my opinion.
I greatly admire Ellsberg's courage and moral consistency.
Yes, somebody should also suggest to the producers to make the film available for on-line purchases (I'm too lazy to be that somebody this time).
You can read the DVD reviews on amazon.com to get the idea how people respond to it. Amazon sells the DVD cheaper than the official site.
