He is best known as series regular Sean Rawlins in ITV crime drama Unforgotten, Gregory in the final series of Peep Show, Walter Hill in Titanic: Blood and Steel and as Newman Noggs in "Nick Nickleby", a BBC adaptation of Charles Dickens novel, The Life and Adventures of Nicholas Nickleby, which he also narrated.
In 2015, besides Peep Show and Unforgotten, Harden also appeared in AMC/Channel 4 co-production, Humans, in David Farr's directorial debut, The Ones Below, and in the long-awaited sequel to British gangster flick Rise of the Footsoldier.
2016 saw Harden feature in a variety of projects, including Irish feature The Truth Commissioner, and in World War II drama Another Mother's Son, as well as on British TV screens in real-life drama The Secret and BBC period drama My Mother and Other Strangers as local drunk, Martin Brady. Meanwhile, he completed filming on Star Wars: The Last Jedi and Stephen Frears' Victoria & Abdul, in which he plays Kaiser Wilhelm II.
Harden's stage credits include Henry Joy McCracken in Stewart Parker's Northern Star at the Finborough Theatre and Children of the Sun at the Royal National Theatre under the direction of Howard Davies.
Harden has also provided voices for several video games, most notably as Xenophilius Lovegood in Harry Potter and the Deathly Hallows: Part I. In 2014, Harden was responsible for bringing a new species in the Halo universe to life on screen, playing Axl in the Ridley Scott produced, Halo: Nightfall.
In 2015, Harden launched In anything at the minute? - The Honest Actors' Podcast, a project centred on interviews with other jobbing actors and available on iTunes.
