Director Michael Harte believes his Dennis Nilsen documentary will reveal how the serial killer got away with his crimes for so long.
Nilsen is believed to have killed up to 15 people, many of them homeless young gay men, after luring them to his London home in the late 70s and early 80s.
He was jailed for life in 1983, with a recommendation he serve at least 25 years, for six murders and two attempted murders. He died behind bars in 2018, aged 72.
Harte made Netflix production Memories of a Murderer: The Nilsen Tapes using more than 250 hours of previously unheard cassettes of the Fraserburgh-born killer’s private recordings from inside his cell.
The filmmaker also had access to 7000 pages of his unedited autobiography.
Harte said: “I feel and believe what we have here is more of a documentary, not about why Dennis Nilsen did what he did but why did he get away with it?
“And how did he get away with it for as long as he did?
“For me, that is (because of) prejudice. It seems he understood prejudice himself, in terms of his background, not just in the police, but just the bigger picture in society.
“Prejudice really allowed it to happen again and again. People had tried to warn others they’d been attacked and they weren’t listened to, for various reasons.”
