Hero Fiennes Tiffin, 20, may have acting in his blood (his maternal uncles are Ralph and Joseph Fiennes) but he’s making a name for himself in his own right after a breakout role in new Netflix drama, Safe.

Starring opposite Dexter’s Michael C Hall and Sherlock’s Amanda Abbington, the young actor played troubled teen Ioan Fuller to great acclaim in Harlan Coben’s gritty drama. Educated at Emanuel School in Battersea, Fiennes Tiffin went on to play a young Voldemort in Harry Potter and the Half Blood Prince, before starring in fashion campaigns for H&M and Dolce & Gabbana. More recently, he's been cast as Hardin Scott in Jenny Gage’s adaptation of Anna Todd’s New York Times YA bestseller, After.
