Olivia Colman portrays a real life murderer in new Sky TV drama Landscapers, penned by her own husband Ed Sinclair.
The Oscar award winner will return to the small screen to star alongside Harry Potter actor David Thewlis as they take on the respective roles of real-life Nottingham couple Susan and Christopher Edwards, who covered up her parents' deaths for 15 years.
The pair buried the bodies of Patricia Wycherley, 63, and her 85-year-old husband William in a garden and stole £300,000 which funded a bizarre fantasy obsession with Hollywood memorabilia.
But it's Colman's benign looking character Susan, who was abused by her father as a little girl, whose delusional obsessions are brought to life in the drama which sets the series apart from typical crime dramas.
Ahead of the show's launch this week, Colman told Sky News : "We find out, through the programme, she faced abuse at the hands of her father as a little girl, and I think it's her escapism to sort of imagine men [can be] heroic and that she finally meets her knight in shining armour."
And ironically by bringing the true-events into a dramatised TV form, the protagonist Susan, who together with Christopher were jailed in 2014, will see her fantasies come to life.
"It must be very strange," Thewlis tells Sky. "You know, Susan's fantasy was the movies and here she is represented in a TV series, she's on the big screen.
"That's a sort of strange twist, isn't it? What will she fantasise about now?"
The Fargo star declared the script was 'perfect' and 'the best thing he'd read in years' adding he was intrigued by the bizarre true facts such as Susan convincing her husband that French actor Gerard Depardieu was his pen pal.
The Broadchurch star later in the same interview lightened added light relief as she joked about her husband Ed's work adding: "If it had been a sh*t script I would have been really nervous.''
But fortunately she was impressed by the script's 'originality and inventiveness' and was intrigued to take on the role.
*Landscapers premieres on Sky Atlantic and NOW on Tuesday 7 December.
