The less you know about the arc of this story the better it's going to play for you. I say that because this is a beautiful puzzle box of a film. This is a film about what happened to Jerry, his life, his family and the making of the film. Its a film that is full layers and as the film goes on doors are opened and the layers of the story are peeled away.
It's a hell of a ride...and a bracing cautionary tale that you need to see.
