Actor Rupert Grint, who played Ron Weasley in the 'Harry Potter' films, took to Instagram to share a post mourning the demise of Robbie Coltrane, who portrayed Hagrid. "I'll never forget the smell of cigars and beard glue - a wonderful combination," he wrote. "[He was]...a giant-hearted man who was still looking out for us even decades later," Rupert added.
