WME has signed British actor Hero Fiennes Tiffin for worldwide representation, with Elan Ruspoli repping him at the agency.
The signing comes on the heels of one of Fiennes Tiffin’s biggest career moments yet. His Prime Video series Young Sherlock, directed by Guy Ritchie, debuted at #1 when it premiered on March 4, 2026.
The show has since reached 45 million viewers, topped charts in 95 countries, and ranks among Prime Video’s Top 10 Originals of all time. A second season is already confirmed.
Prior to Young Sherlock, Fiennes Tiffin appeared in Ritchie’s Lionsgate film The Ministry of Ungentlemanly Warfare alongside Henry Cavill and Eiza González, and starred opposite Simone Ashley in the Prime Video rom-com Picture This, which also debuted at #1.
He first gained recognition playing the young Lord Voldemort in Harry Potter and the Half-Blood Prince, the villain portrayed by his uncle, Ralph Fiennes.
Up next, he stars with Idris Elba and Caitlin Fitzgerald in Lionsgate‘s survival thriller Above the Below, directed by Elba.
WME’s signing spree has been relentless in 2026. The agency recently added actress Sophia Lillis and Saturday Night Live breakout Jane Wickline, signaling an aggressive push to lock in rising talent across film and television.
Fiennes Tiffin continues with The Artists Partnership and Shemarya Artists for representation and The Initiative Group for publicity.
