“The drama also stars Alexa Davies, from Rhyl, as Jeremy Bamber's girlfriend at the time of the murders, who played an important role in the investigation.
Davies portrays Julie Mugford in the ITV series. Her second statement to police in September 1985 led to the arrest of Bamber.
In this statement, which reportedly differed from her initial account, Mugford alleged her boyfriend had been planning to kill his family.
The situation was complicated for the 20-year-old though, as expressed recently by Davies - who is best known for her role in 2018's Mamma Mia! Here We Go Again.
The 24-year-old said Mugford had "so many things to consider" and was ultimately "left with this choice to make."
She said the choices were between "doing the right thing and go to the police even though she had no evidence and didn't really have any reason to think anyone would believe her," and "keeping it to herself for the rest of her life, which would be a very selfish thing to do.
She added: "But she was 20 and in love and just wanted to get married and to have her life with this man."
The six-part series has been described by ITV bosses as a "fascinating insight" into what happened on that fateful night in 1985.
Speaking to the RadioTimes, she said: "From reading the scripts and research and meeting Paul [Whittington, the director], there are so many layers to this story and so many layers to her."
Willow Grylls, executive producer for New Pictures, said: "This notorious case has been the subject of much debate, and our programme focuses on the impact of the human tragedy."
And writer Kris Mrksa added: "This is an incredibly compelling true crime story, but it's the human dimension of these events that gripped my imagination, particularly after reading Colin Caffell’s book.
"So much discussion of the case has focused on contested legal details, but I wanted to tell this story in a way that did justice to the devastating emotional truth of what happened."
