Fiennes Tiffin made his first film appearance as Spartak in the 2008 drama film Bigga than Ben. He was subsequently cast as 11 year-old Tom Riddle in Harry Potter and the Half-Blood Prince, out of thousands of young actors who auditioned for the role. Although at least one publication alleged that his family connections alone helped him get the part, director David Yates said he was cast due to his ability to find 'the darker space' in his line readings, and that he did not get the role solely due to his relation to Ralph Fiennes, his uncle, who played Lord Voldemort. However, Yates did admit that the family resemblance was a "clincher".Jensen, Jeff. "There Will Be 'Half-Blood.'". Entertainment Weekly, Iss. #1007/1008, 22/29 August 2008. pg. 39. Retrieved on 19 August 2008. Yates described Fiennes Tiffin as "very focussed and disciplined".Puig, Claudia. "'Potter' trailer unveils a young Voldemort." USA Today, Life section, 30 July 2008. Retrieved 19 August 2008. He said Fiennes Tiffin "got the corners and dark moods and odd spirit of the character", as well as having a "wonderful haunted quality that seemed to bring Tom Riddle alive on-screen for us".
