After filmmaker Raoul Peck made his award-winning James Baldwin documentary \u201cI Am Not Your Negro,\u201d he had a lot of suitors in Hollywood. But it was HBO that didn\u2019t blink when Peck explained what he wanted to do next: a project about colonization, extermination and genocide. That evolved into "Exterminate All the Brutes," a four-part series that zigzags through 700 years of colonial history.
