Early life and education
Early life and education
He is the twin brother of actor Luke Treadaway.
Born at the Royal Devon and Exeter Hospital in Exeter, Devon, Treadaway was brought up in Sandford, Devon. His father is an architect and his mother is a primary school teacher. Treadaway attended Queen Elizabeth's Community College in Crediton, Devon, where he played in the twice Devon Cup winning Rugby Union team. Inspired by a love of Eddie Vedder and with support from their secondary school drama teacher, Harry and his twin brother Luke formed a band called Lizardsun. They also both joined the National Youth Theatre. Treadaway studied acting at LAMDA and graduated in 2006.
Career
Career
While still at drama school, he had his professional debut in Brothers of the Head, alongside his twin brother Luke Treadaway, a feature film about conjoined twin brothers in a punk rock band. He played Tom Howe, the band's rhythm guitarist and songwriter, and his brother Luke played Barry Howe, the lead singer. The Treadaways performed all tracks featured in the film themselves live on stage, as well as recording nine tracks for the sound-track album. In 2007, he acted in the Tiger Aspect film Recovery. He starred as Mark Brogan on the Channel 4 series Cape Wrath (known as Meadowlands in the United states). Treadaway played Joy Division drummer Stephen Morris in the film Control (2008). He appeared in the Channel 4 television movie The Shooting of Thomas Hurndall in 2008. In 2009, he starred in the Johnny Kevorkian–directed horror film The Disappeared and the children's science fiction-fantasy film City of Ember. That same year, he made his stage debut in Over There, a play by Mark Ravenhill, alongside his twin brother Luke at the Royal Court Theatre. In 2011, he starred as title character James Furlong in the Irish film The Last Furlong. In 2014, he played Victor Frankenstein in the Showtime TV series Penny Dreadful. In 2016, he was cast in a leading role in Audience's Mr. Mercedes, based on the Stephen King novel. His part was that of Brady Hartsfield, a brilliant young psychopath who decides to engage in a cat-and-mouse game with Brendan Gleeson's Bill Hodges. Anton Yelchin had originally been given the role of Hartsfield, but following Yelchin's death in June 2016, it was announced that his role had been recast with Treadaway assuming the part. In 2019, Treadaway played Roddy Llewellyn in the third series of Netflix's The Crown. He portrayed the Romulan Narek in the first season of CBS All Access's Star Trek: Picard.
