Vicky McClure feels "privileged" to have been cast in a new drama about the Warrington bombing.
The 34-year-old actress will appear in "Mother's Day" as Dubliner Susan McHugh, who led a peace demo of 20,000 after the explosion in March 1993 and is honoured to be portraying the "inspirational" mother in the one-off 90-minute drama.
She said: "Susan McHugh's actions back in 1993 remain just as inspirational today as they were 25 years ago. I feel truly privileged to play her in this incredibly moving new film."
Susan organised one of the largest peace rallies in Irish history in protest at continued violence after becoming outraged by the tragic deaths of Johnathan Ball - who was out shopping for a "Mother's Day" card with his babysitter - and 12-year-old Tim Parry in the blast.
Joining Vicky in the drama will be David Wilmot as her husband Arthur McHugh, her "Line of Duty" co-star Daniel Mays and Anna Maxwell Martin as the parents of victim Tim.
Anna said of the BBC drama: "I know that many will recall the bravery and dignity shown by the families affected by the Warrington bombings. It's a real honour to be telling their story."
The script has been written by "Murdered For Being Different" screenwriter Nick Leather, who has been wanting to work on a project so close to his heart since he began his career.
He said: "As someone who grew up in Warrington and was on my way into town on the day of the bombing, bringing this astonishing story to the screen has been a career-long mission.
"Over the last year, I've been fortunate to work with a wonderfully supportive team at the BBC, including the director Fergus O'Brien, and have found the Parry and McHugh families to be even more inspiring than I did as a kid. I hope people are as moved and affected by this drama as we have been making it."
