Louis Theroux

Louis Theroux is a British-American broadcaster. He is known best for his Gonzo style of journalism. This style of journalism is similar to reflexive journalism. It is famous for sarcasm, exaggeration, humour and profanities and is written subjectively, in the first person narrative, including the reporter as a part of the story. This style of documentary uses personal experiences and emotions and is more partial to worrying that the style is appropriate than the actual accuracy of the facts.
Louis Theroux is famous for his show 'Louis Theroux's Wierd Weekends' which showed footage of everything controversial including 'Porn Stars and 'U.F.O. Hunters' in January 1998, 'Swingers' and 'Black Nationalism' in early 1999, and 'Thai Brides' and 'Gangsta Rap' in October of 2000. What made this more controversial was the time at which he did it. 10 years later in 2010 shows like this wouldnt be considered as daring as they were then. In 1998 this was very risky as people rarely spoke up about issues like these.

Here is an example of some of his work where he interviews one man during his filming of 'U.F.O. Hunters'
