Several Harry Potter costars honored McCrory, who played Narcissa Malfoy in the final three Harry Potter films.
Tom Felton, who portrayed McCrory's onscreen son Draco Malfoy, wrote in an Instagram post, "So sad to say farewell so suddenly - I never took the chance to tell her, but she helped shape me as a person so much - on & off screen."

Jason Issacs reflected on McCrory's legacy in his own post, writing, "Decades ago Helen and I auditioned together for a film. I came home and said to [my wife] Emma 'I think I've just met the greatest actress I've ever seen.' After years of watching her mesmerize audiences I don't think that any more...I know it."
"Luckily, I eventually found out that she was also scabrously funny, shockingly naughty and with an empathetic heart the size of a planet. As continually starstruck as I was on the Harry Potter films, being screen-married to and giggle with the great Helen McCrory will always be a highlight," he added. Her proudest achievement, though, was building and loving the family that was her bedrock. They've lost so much and I send all my love to Damian and the kids. xxx."
"I truly couldn't believe this news when I heard it. Helen was one of the most incredible actors I got to work with on the Harry Potter films," his statement read. "She was effortlessly commanding and captivating as an actor, as well as being kind, generous and incredibly good fun as a person."
"Also, as it happens, she's one of the absolute coolest people I've ever met, in that I can't ever imagine her being flustered or nervous, she always seemed totally assured of who she was and what she was doing," Radcliffe, 31, added. "She was a supreme talent and a wonderful person and will be very greatly missed."
Harry Potter creator and author J.K. Rowling also shared sweet sentiments about McCrory, tweeting, "I'm devastated to learn of the death of Helen McCrory, an extraordinary actress and a wonderful woman who's left us far too soon. My deepest condolences to her family, especially her husband and children. Simply heartbreaking news."
McCrory also starred as Polly Gray in the series Peaky Blinders opposite Cillian Murphy, who mourned her death in a statement shared on social media.
"I am broken-hearted to lose such a dear friend. Helen was a beautiful, caring, funny, compassionate human being," Murphy, 44, said. "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," he continued. "My love and thoughts are with Damian and her family."
Meanwhile, Helen Mirren honored the late star with a black-and-white photo, writing, "A great actress and a great person. this is so very very sad."
