I love ESPN’s 30 for 30. I adored the one on Andre Agassi. I love the story, the documentary on Ray Mancini’s life. This is food for my soul. I love the inside story because that’s kind of the world I live in. And a lot of the stories I can’t tell, but I have such deep appreciation when the honesty and authenticity of an athlete is out there.

They wanted it for its artistic value. I found that deeply moving.

I’ve actually got a huge, huge list of documentaries that I’ve been meaning to watch, many of them collected from the guests in your Tools of Titans book. The one I did watch and enjoy is actually a series rather than a documentary; the remake of Cosmos. ... The topics he covered in those episodes was so stunning, and it was a great education for my son who is very, very into science himself. So that’s the documentary that stands out in my mind, probably the most interesting thing in the last five years, anyway.

My favorite documentary is one called Up. ... For your listeners, it’s a guy, Michael Apted who in 1964 decided to follow about a dozen or actually more kids from very different backgrounds and from the UK and some in orphanages, and some very well off to try and establish how much people are stuck to their context, to their social context. ... It’s quite an extraordinary way to look at humanity and see can people really escape their social constraints and their initial lay of life?
