The wait is nearly over.

It's been a while since Louis Theroux has been on our TV screens but we don't have long now until he's back on the television again. His new three-part series is set in America and will focus on assisted suicide, adoption and polygamy, and it looks like it could be a return to Weird Weekends form. "I have always been interested in how people conduct the most intimate aspects of their lives," said Theroux. "For this series we looked at the new ways Americans are approaching some of humanity’s oldest dilemmas: pregnant mums who feel unequipped to keep their babies and so pick new parents for them; the world of polyamory aka 'ethical non-monogamy'; and people with debilitating conditions who opt to hasten their own deaths." The latest trailer is only a minute long but shows some of the most emotional parts of the series.
