David is best known for his roles in Good Omens and Broadchurch. Daniel has starred in Line of Duty and Temple, while Jason has been seen in The Crown and The Lost Honour of Christopher Jefferies.
Nilsen murdered boys and young men in his flat from 1978 to 1983.
He was undetected for five years, and it was only when DCI Peter Jay was called to 23 Cranley Gardens on 9 February, 1983, to investigate human fragments of flesh and bone clogging the drains, that the police realised they had a serial killer on their hands.
