What is The Nilsen Files about?
The Nilsen Files looks at the crimes of Dennis Nilsen, who was found guilty of murdering six young men in 1983.
Produced by The Shipman Files filmmaker Michael Ogden, the series will look at whether prejudices at the time had a part to play in Nilsen not being discovered earlier.
Focusing on the lives of the victims, Ogden will ask why, 40 years on, they remain just a footnote in this terrible case. He will explore not just who these boys and young men were, but also how attitudes at the time allowed their disappearance and murders to be overlooked.

The synopsis reads: “As Nilsen’s crimes are discovered, the truth about his victims reveals prejudice and multiple missed opportunities to catch a murderous predator.”

“Examining Nilsen’s high-stakes trial and the dramatic emergence of witnesses to his crimes. The cases of survivors reveal how chances to catch Nilsen years earlier were missed,” the summary reads.

Dennis Andrew Nilsen was a Scottish serial killer and necrophile, which is a person who is sexually attracted to corpses.
Between 1978 and 1983, he murdered at least 12 young men and boys in London.
Nilsen became known as the Muswell Hill Murderer, as he committed his later murders in the Muswell Hill area of North London.
In 1983, Nilsen was convicted at the Old Bailey for six counts of murder and two of attempted murders. He was sentenced to life imprisonment, with a recommendation that he serve a minimum of 25 years. This was later changed to a whole life tariff in December 1994, with no possibility of parole or conditional release.
Nilsen died in hospital in 2018, due to a pulmonary embolism and a retroperitoneal haemorrhage, which occurred following surgery to repair an abdominal aortic aneurysm.
Is there a trailer for the Nilsen Files?
The BBC previously released a 30-second trailer for the documentary. In the clip, the narrator says: “This was a monstrous series of screw ups… All those lives could have been saved.”
A contributor adds: “He gets so much voice. None of the victims have had a voice.”
