Raphael Coleman, a former child actor who turned into a climate change activist, has expired. He had been 25.

Coleman passed away on February 6, his mother shared on societal media on the weekend.

“Rest in peace my beloved son Raphael Coleman, aka Iggy Fox. He died doing what he loved, working for the noblest cause whatsoever. His family couldn’t be prouder. Let us observe all he achieved in his short lifetime and treasure his heritage,” his mum, Liz Jensen, shared on Twitter.

Coleman was created in September 1994 at Wandsworth, England. Fans probably remember him because of his role as Eric from the 2005 household humor Nanny McPhee, together with Emma Thompson and Colin Firth. In addition, he appeared in the movies It’s Alive (2009) and The Fourth Kind (2009).

He died abruptly after falling while out on a jog. His cause of death hasn’t yet been published.
