Tom Felton, who’s best known for his role as Draco Malfoy in the Harry Potter films, payed tribute to the actress who played his mother, Helen McCrory after she lost her battle with cancer late last week.

“So sad to say farewell so suddenly,” Felton wrote in an Instagram post alongside a photo from the films. “I never took the chance to tell her but she helped shape me as a person so much—on & off screen—She was always relentlessly herself—razor sharp wit—silver tongued—kind & warm hearted—she suffered no fools yet had time for everyone—thank you for lighting the way forward & holding my hand when I needed it xx.”

Felton wasn’t the only Harry Potter actor to pay her tribute. Daniel Radcliffe recalled the late actress in a statement. “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,” he said. “She was effortlessly commanding and captivating as an actor, as well as being kind, generous and incredibly good fun as a person.”

He continued, “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. She was a supreme talent and a wonderful person and will be very greatly missed.”

The Peaky Blinders star’s husband, Damian Lewis, shared the news of her passing in a Friday tweet.

“I’m heartbroken to announce that after an heroic battle with cancer, the beautiful and mighty woman that is Helen McCrory has died peacefully at home, surrounded by a wave of love from friends and family,” he wrote. “She died as she lived. Fearlessly, God we love her and know how lucky we are to have had her in our lives. She blazed so brightly. Go now, Little One, into the air and thank you.”
