The header of the piece pays tribute to the young man, who was described as a "burning bright soul." “James ‘Iggy’ Fox died on 6 February. He was 25, had given up a career in science to join XR and fought hard for the cause, especially for Indigenous rights. Iggy was a burning bright soul and he will be deeply missed by us all," it reads. His stepfather Carsten Jensen also paid tribute to him on Facebook [via EW]. "As a child, he was old-wise, extremely literate and loved to lecture adults with his always astonishing knowledge,” he said. “He was a child actor in the popular British Comedy Nanny McPhee, where he played himself with great talent, a little redhead boy who was always mixing explosive chemical ingredients. He had several roles, was rewarded and could have chosen a career as an actor. But he wanted to be a scientist, not to blow up something, as his figure in Nanny McPhee, but to save the planet.”
