Hero Fiennes-Tiffin

Hero Beauregard Fiennes-Tiffin (born 6 November 1997) is an English actor best known for his role as the 11-year-old Tom Riddle, the young version of antagonist Lord Voldemort (played in the films by his uncle, Ralph Fiennes), in Harry Potter and the Half Blood Prince, the sixth installment of the Harry Potter films.

Fiennes-Tiffin was born on 6 November 1997 in London, to film directors George Tiffin and Martha Fiennes, and educated at Emanuel School.

Fiennes-Tiffin made his first film appearance as Spartak in the 2008 drama, Bigga Than Ben. Fiennes-Tiffin earned the part of young Voldemort even though thousands of young actors auditioned for the role; at least one publication, however, has alleged his family relation alone landed him the part. David Yates, director of Harry Potter and the Half-Blood Prince, said Fiennes-Tiffin was cast as Tom Riddle due to his ability to find "the darker space" in his line readings. Yates said he did not get the role due to his relation to Ralph Fiennes, who was his maternal uncle, but admitted the family resemblance was "a clincher". Yates described the actor as "very focused and disciplined" and said he "got the corners and dark moods and odd spirit of the character" and had a "wonderful haunted quality that seemed to bring Tom Riddle alive on-screen for us."
