Only Louis Theroux could make an insanely good Scientology documentary without actually talking to any Scientologists.
After being fobbed off by the church for years, Louis decided instead to make a recreation of Scientology's darkest practices, as informed by the self-proclaimed former "baddest ass dude in Scientology", Marty Rathbun.
But of course, there's so much more than that.
The newly-released trailer shows old Lou being intimidated by various Scientologists, who trail, film, and question him in a segment. It looks to be a weird, wonderful, and mildly terrifying examination of the church.
The film is released in the UK on October 7, and there will be a live Q&A with Theroux at Royal Festival Hall on October 10.
