“We knew if we were ever going to do this, it had to be the right time and the right team,” Will said at Sundance in January. “And we would give out our archive and our home movies, make ourselves available for some raw and vulnerable interviews and then put all our faith in the team that had assembled around us and see what they would get back.”

“And the end result is remarkable, so our trust has definitely been rewarded,” he added as the audience burst into applause.
