Actor Cillian Murphy, who starred alongside Helen McCrory in Peaky Blinders, has led tributes to the late actress.
Mr Murphy said he was "broken-hearted to lose such a dear friend."
“Helen was a beautiful, caring, funny, compassionate human being.
“She was also a gifted actor – fearless and magnificent. She elevated and made humane every scene, every character she played.
“It was a privilege to have worked with this brilliant woman, to have shared so many laughs over the years.
“I will dearly miss my pal. My love and thoughts are with Damian and her family.”
Aisling Bea, who starred with Helen McCrory in the 2020 ITV drama Quiz, tweeted out her condolences.
“Utterly heartbreaking, what a loss," she wrote.
"Every actor looks & looked up to Helen McCrory – so brilliant and gripping and transformative and those who knew her as a friend really loved her.
“On Quiz last year & she was just so bloody cool, with funny anecdotes & stories and worrying about remembering all her lines.
“I could not believe that THE Helen McCrory was pacing up & down, worried about lines, she was so down to earth & openly vulnerable, all for the craft & being as good as possible.
“Then we watched her in the courtroom pretty much do a one-woman monologue and be incredibly excellent and not forget a thing. #RIPHelenMcCrory Thoughts go out to her family and friends.”
Actor Jim Howick, who worked with Helen McCrory and her husband, Damian Lewis, on the 2015 comedy film Bill, tweeted: "This is so shocking and sad. Helen along with Damien were both terrific fun on Bill.
