The show, which premiered on May 6 in the US and May 7 in the UK and Ireland, is a 5-episode mini-series that chronicles the 1986 nuclear disaster in the then Soviet-controlled Ukraine and its devastating aftermath.

In the show, Co Kerry native Jessie Buckley plays Lyudmilla Ignatenko, a pregnant woman whose fireman husband was one of the first responders to the disaster. Though parts of the mini-series are fictionalized, Buckley’s character is based on a real person.

Buckley told The Irish Mirror: “The script completely blew me away.”

“I wasn’t born when it happened but when I was at primary school there was a charity set up by Adi Roche for children affected by the explosion. They would come and live in Ireland for a year and go to my school. So I felt very emotionally involved.”

“But the pressure is your responsibility to tell these people’s stories.”

“There was one day I was on set and there were various extras from Lithuania and Ukraine.”

“There was this woman beside me crying her eyes out. At the end, I gave her a hug and she said her son had been a victim of that explosion.”

Barry Keoghan, who made his acting debut in RTE’s drama ‘Love / Hate,’ features in four of the five episodes as Pavel, whose duty as a soldier is to kill any infected dogs wandering the area.

While filming ‘Chernobyl’ in 2018, Keoghan told the Irish Independent: "I have turned down a lot this year waiting for the right thing to come along, so fingers crossed."

Having starred in films such as 'Dunkirk' and 'The Killing of A Sacred Deer,' Keoghan has proven that he has fine taste in choosing acting roles.
