The master of the documentary genre, Louis Theroux has been killing it ever since he first started making films in the late 1990s.
And ohhh boy get yourselves snuggled in on the sofa for a good one tonight, because his famous My Scientology Movie is showing on BBC Two tonight at 9pm.
What's it all about?
After the Church of Scientology refuses to cooperate in making a documentary, Louis Theroux teams up with former senior church official Mark Rathbun to create dramatic reconstructions of incidents within the church witnessed by Rathbun and other ex-Scientologists. They focus in particular on alleged violent behaviour by the church's leader David Miscavige at its secretive Gold Base facility in California, which Theroux visits.
The church retaliated by putting Theroux and his film crew under surveillance, leading to camera-wielding confrontations with a Scientology "squirrel buster" team and with church officials outside Gold Base.
Grab the microwave popcorn - this is a real gem.
