The source material for this film is the memoir LAST THOUGHTS WHILE VANISHING FROM THE FACE OF THE EARTH by Louis Sarno, but that text is significantly different from this film. Number one for me, the protagonist "Larry", is nowhere near as charming nor funny as the real Louis Sarno, though the character evidently has some of the same diseases as him. Louis was hired as an advisor and facilitated actual Aka (pygmy) people appearing in the film. They are the most authentic part of it, along with locations in the Central African Republic. Within that country relations among people and groups can be quite complicated (well-shown in Sarno's text,) but for dramatic effect a logging company becomes the chief adversary and the actor Isaach De Bankolé is wasted as a one-note villain.
