In most cases this means interviewing people with extreme beliefs of some kind, or just generally belonging to subcultures not known to exist by most or just frowned upon.

To me, it's almost a privilege to be welcomed into these communities and to shine a light on them and, maybe, through my enthusiasm, to get people to reveal more of themselves than they may have intended.

I'm not a matinee idol disguised as a nerd.In 2005 Louis released a book called The Call of the Weird: Travels in American Subcultures where he revisits people he previously interviewed for the Weird Weekends documentaries.

He tracks down Thor Templar (alien resistance commander), JJ Michaels (porn star), Ike Turner (musician and ex-husband of Tina, from an uncompleted episode), Mike Cain (survivalist), Haley (prostitute), Jerry Gruidl (Aryan Nations), Mello T (pimp turned rapper), Oscody (survivor of Heaven's Gate, also from an incomplete episode), Marshall Sylver (Hypnotist), and Lamb & Lynx (the singing White Nationalist twins – aged 11).
