While Simpson was not convicted in that criminal case, he was found to have committed the killings by a civil court. Simpson has spent the past nine years in a Nevada prison for taking part in an unrelated 2007 armed robbery.
The former football great will turn 70 in July when he'll also be eligible for parole. It's possible that Simpson will become a free man in the months that follow.
Though very few people have spent more time studying the former running back than Edelman, the 42-year-old Brooklyn-based filmmaker said he doesn't know whether Simpson will be looking to do interviews if and when he's finally granted parole.
"I have never talked to the man I don't know him," he says. "I do not profess to be inside his head."
With the Simpson documentary under his belt, Edelman says it's important for filmmakers to stay focused on the world around them, which includes the world of sports and the political arena.
"The power of storytelling will always be here to engage an audience, especially in a film like ('O.J.: Made in America'), which deals with a very decisive period in our culture," he said. "And I feel it's more important than ever for the next four years."
