Louis Theroux’s Weird Weekends is a television documentary series, in which Louis Theroux gives viewers the chance to get brief glimpses into the worlds of individuals and groups that they would not normally come into contact with or experience up close. 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. It was first shown in the United Kingdom on BBC2. In 2001, Theroux was awarded the Richard Dimbleby Award for the Best Presenter BAFTA for his work on the series.
