This documentary premiered in November 2014. I just watched it on PBS. It will be on next on Jan 6 at 7 PM CT. I thought it was good to see the family talk about him.

"A fresh look at the enigmatic story of a young American hiker named Chris McCandless, who was found dead in an abandoned bus in the Alaskan wilderness and became the subject of the best-selling Jon Krakauer book and Sean Penn-directed movie “Into the Wild.” Chris McCandless' own letters, released for the first time, as well as new and surprising interviews probe the mystery that still lies at the heart of a story that has become part of the American literary canon and compels so many to this day."
