Watch the first footage from Leonardo DiCaprio's creepy Jonestown massacre documentary

The Jonestown massacre was one of America’s biggest tragedies, in which fanatical cult leader Jim Jones convinced more than 900 of his followers to drink cyanide-laced Kool-Aid. It’s an infamous story that has been told numerous times through documentaries and movies, but this latest four-parter aims to be the most in-depth of them all.

Co-produced by Leonardo DiCaprio, Jonestown: Terror in the Jungle is based on the work of investigative journalist Jeff Guinn and uses real-life archival footage, dramatic recreations and the all-important new and exclusive interviews from those involved in the incident.

It won’t be an easy watch, due to its airing of real-life footage and horrendous audio clips of the actual massacre, but it’ll be a fascinating one all the same - the power that one man had over so many was almost unheard of. It’s almost never a good thing when that happens, is it? No need to mention any more names…

Here’s the first trailer:

And you can see an extended look at Jim Jones as a child, over at EW, here.

The doc will air on America’s SundanceTV on Saturday November 17 and conclude the following night. Presumably we’ll get it on Netflix or similar, a tad later, and we can’t wait.
