A new documentary-style series on the murder of Sophie Toscan du Plantier by director Jim Sheridan and journalist Donal MacIntyre is due for release on Sky next year.
The production companies behind the five-part series claim it will show "original" evidence and "never-before-seen footage" in the notorious case.
Sheridan recorded hundreds of hours of footage over five years for the series and also appears in front of the camera.
Titled Murder at the Cottage: The search for justice for Sophie, the series will examine the circumstances surrounding the brutal killing of the young French TV producer in Schull, Co Cork in 1996.
The series also promises interviews with those closest to the case, including access to Sophie's family and to Ian Bailey, who was found guilty of murder in absentia by a French court in 2019 and sentenced to 25 years in prison.
He has been twice arrested in Ireland but was never charged here in relation to her death.
Former journalist Mr Bailey has successfully fought repeated extradition attempts from the French authorities.
He still lives in west Cork and maintains his innocence.
Dublin director Sheridan, who narrates the series, said: "This is a story that has fascinated me for over two decades.
"It's a murder that carries implications for the meaning of justice in Ireland, in France and in the UK, that calls into question the meaning of Europe, as the convicted man in France is free in Ireland.
"It's a story that calls into question the meaning and process of the police and the legal system. It's a story that shines a light on domestic violence.
"I would like to thank all those who have contributed to this series but in particular to Sophie's family, who are still searching for justice," he added.
The six-time Oscar nominated director worked on the series with Donal MacIntyre, who has a production company, Dare Films.
The series is produced by Hell's Kitchen in association with Sky Studios.
Sheridan, who previously directed My Left Foot, In America and In the Name of the Father, also produced the series, along with MacIntyre.
The series is expected to air on Sky Crime next year, while a separate three-part documentary series on the murder will also be released on Netflix.
