"Robbie was like the most fun uncle I've ever had, but most of all, he was deeply caring and compassionate towards me as a child and an adult," Watson wrote in an Instagram Story. "His talent was so immense that it made sense he played a giant — he could fill ANY space with his brilliance."
Watson continued, "Robbie, if I ever get to be so kind as you were to me on a film set I promise I'll do it in your name and memory. Know how much I adore and admire you. I'll really miss your sweetness, your nicknames, your warmth, your laughs, and your hugs. You made us a family. Know you were that to us. There was no better Hagrid. You made it a joy to be Hermione."
