Brand, 39, is the subject of the picture which has been in production for the past seven years under the same number of directors. Director Ondi Timoner eventually took over the reigns of the film and said Friday she predicted the actor would likely back out of the premiere.
"He watched it and he had a hard time -- really hard time with it," she told IndieWire Friday. "I really wanted him to be at peace with this film, but I don't know if he'll ever really be at peace with it. It's so raw and so personal and he's never let anything like this out before."
