Nicola’s sister Louise Cunningham, along with her parents Ernest and Dorothy Bulley and partner Paul Ansell, revealed the impact of the public scrutiny on their lives in the documentary.
Director Rachel Lob-levyt, who worked on Louis Theroux Interviews and Hospital, told the Radio Times the “family tell their story in their own words, unfiltered”.
She said: “We had a viewing with the family. It was difficult – obviously emotional for them. They feel the documentary really honours their experience, and honours Nikki.
“At the time she went missing, Paul was subject to a really difficult level of scrutiny.
“The idea of putting himself back in the public eye is nerve-racking but ultimately, he thought it the right thing to do.”
