Rod Roddenberry took camera and crew on a journey to discover more about his late father, Star Trek creator Gene Roddenberry, and compiled it all into the documentary Trek Nation. “Rod’s quest takes him boldly beyond fandom to a deeper understanding of one of the most hugely influential sci-fi entities of all time” and gives us a better understanding of the man who started it all.
Mr. Roddenberry was good enough to give me some of his time and discuss Trek Nation in a little more detail.
You can watch preview clips of the film at the Science Channel website.
