Dominic West has recurring "nightmares" since playing serial killer Fred West.
The 41-year-old actor portrays the notorious murderer - who along with wife Rose killed at least 12 young women - in forthcoming ITV drama 'Appropriate Adult', and admits the role is still haunting him.
He said: "I have this recurring dream where I'm perched on a wall and Fred West is trying to grab me and pull me down but I didn't let him get to me. I was determined not to."
Despite the horrific nature of Fred West's crimes, Dominic insists the drama won't be "sensational" and believes there is an important message to the story.
He added in an interview with Radio Times magazine: "The production team have found a way of telling this story through the eyes of a social worker who was sent to interview West in prison.
"I think it's effective without being sensational in any way.
"Thousands of people still go missing in this country every year and are never found. Fred West preyed on runaways without being caught for 25 years. We should not forget this case, because there could be others like him."
