Production has begun on the film The Lost Children of Tuam, the story of local historian Catherine Corless and her research into the former mother-and-baby home in Tuam, Co Galway.
Research by Catherine Corless found that there were no burial records for almost 800 babies and infants who died at the home over a 36-year period.
Excavation of the site began in July.
The Lost Children of Tuam is directed by Frank Berry (Aisha, Michael Inside) and stars BAFTA and Olivier Award winner Monica Dolan (Mr Bates vs The Post Office, Appropriate Adult) as Catherline Corless.
Liam Neeson and Catherine Corless are among the producers of the film, which is presented by BBC Film and Fís Éireann/Screen Ireland in association with Coimisiún na Meán, RTÉ, Ireland's Port Pictures, and the Dublin-based Element Pictures, among others.
The award-winning playwright and screenwriter Rebecca Lenkiewicz (Hot Milk, Her Naked Skin) has written the script for The Lost Children of Tuam.
It is based on the 2017 New York Times article of the same name by Dan Barry, which was optioned for the screen by Liam Neeson.
Co-producer Catherine Corless described seeing a "dedicated, professional and high-profile film crew" bringing the story to the screen as "a great honour".
"It's startling, too, that I have observed the passion with which Frank Berry and his team are ensuring that the truth of what happened is paramount, and I am grateful, for that has been the essence of my long journey," she continued.
"It is said that a good film is immortal, and I have no doubt that The Lost Children of Tuam will come under that spotlight."
Producer Liam Neeson said he is "so honoured and proud" that the film is in production after "eight years of preparation".
He described the film as "a profound story of one woman's relentless pursuit and dedication in uncovering the horrific truth of the events in Tuam that shocked our nation to its core and is still reverberating in every aspect of our society".
Director Frank Berry said it is "a privilege" to make The Lost Children of Tuam.
"As Catherine has said, we must face this history, and our hope is that this film makes a meaningful contribution to that process," he continued.
"We have a remarkable cast, led by the amazing Monica Dolan, and crew who are all approaching this subject with great care and sensitivity, aware of its deep significance in Ireland and beyond."
