Ireland’s Tánaiste (deputy prime minister) Simon Harris said he was “deeply saddened” by the death of “a national treasure”.
“She was a consummate performer who graced our screens and stages with remarkable talent and authenticity. Brenda brought depth and humanity to every role she undertook,” he said.
“She truly was among the greatest exports this country has ever produced and an ambassador for Irish talent on the world stage. Quite simply, we will never see the like of her ever again.”
The US ambassador to Ireland, Edward Walsh, paid tribute to Fricker as “a giant of Irish film” and praised her “unforgettable” performance in My Left Foot.
Writing on X, external, he said: “From Dublin to Hollywood, her work brought Ireland’s stories to the world and inspired generations on both sides of the Atlantic.
“She leaves a remarkable legacy, and I extend my deepest condolences to her family, friends, and all who loved her.”
Fricker’s former Casualty co-star Cathy Shipton, who played Lisa ‘Duffy’ Duffin, also paid tribute, describing Fricker as “one of the most authentic people I’ve ever met”.
Shipton told BBC News: “She lived her life courageously warts and all. I loved her for her wit, her intelligence and her brilliant sense of humour. Life happened when you were around Brenda. We shared a love of dogs – collies and my girl Juno is named after her favourite collie.
“I love her and miss her and am so glad l knew her.”
