Hero Fiennes Tiffin was born in London on 6 November 1997, and is the son of film director Martha Fiennes and cinematographer George Tiffin.^[2] He has an older brother named Titan and a younger sister named Mercy.

Fiennes Tiffin made his first film appearance as Spartak in the 2008 drama film Bigga than Ben. He then landed the part of "11-year-old Tom Riddle" in Harry Potter and the Half-Blood Prince out of thousands of young actors who auditioned for the role.^[7] 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 plays Voldemort. However Yates did admit that the family resemblance was a "clincher".^[8] Yates described Fiennes Tiffin as "very focused and disciplined"^[9] and said he "got the corners and dark moods and odd spirit of the character",^[7] as well as having a "wonderful haunted quality that seemed to bring Tom Riddle alive on-screen for us".^[9]

After Harry Potter, Fiennes Tiffin then landed British television roles in Private Peaceful (2012) and Safe (2018), as well as a short independent film called Possession with Intent to Supply (2016).

The last three films were filmed simultaneously in Bulgaria in late 2020,^[10] due to the COVID-19 pandemic.
