Career
In 2010 James made his television debut in two episodes of A Passionate Woman. The same year he played Turkish diplomat Kemal Pamuk in an episode of the first season of Downton Abbey. His film credits include You Will Meet a Tall Dark Stranger (2010). James was cast in Stranger while still in his final year at drama school. He was named a "Star of Tomorrow" in 2009 by Screen International.
In 2011, James starred in the short-lived horror series Bedlam, playing the lead role of Jed Harper. That same year, he also played James, an obnoxious night club rep, in the British comedy The Inbetweeners Movie (2011). In 2012 James appeared in the miniseries Room at the Top as Jack Wales and ITV's Case Sensitive as Aiden Harper. He was in the films The Domino Effect (2012) and Underworld: Awakening (2012), playing the role of David in the latter opposite Kate Beckinsale. He reprised his character David in the fifth Underworld film, as the film's male lead. James starred as Detective Walter William Clark Jr. in the American crime-drama series Golden Boy (2013), which aired for one season.
James' breakthrough role was his portrayal of Tobias "Four" Eaton in Divergent (2014), a film adaptation of Veronica Roth's novel of the same name. He reprised the character in the sequel, The Divergent Series: Insurgent (2015). He returned in one more Divergent film, The Divergent Series: Allegiant (2016). James performed his own stunts in the film series.
James starred alongside Amber Heard, Billy Bob Thornton and Jim Sturgess in the film adaptation of London Fields, and in the indie drama The Benefactor (2015), with Richard Gere and Dakota Fanning. James executive produced and starred as Michael in Backstabbing for Beginners (2018). He starred as Will Younger in the Netflix film How It Ends (2018). In 2019 James executive produced and played Sidney Parker in the British series Sanditon as a male lead.

He then executive produced and starred in the film Lying and Stealing. James launched his own film and TV production company, named Untapped, that same year.
James produced and appeared in the 2020 science fiction film Archive, playing a robotics scientist working on a secret project involving building a prototype based on his dead wife. He starred in the romance series The Time Traveler's Wife, which premiered in May 2022. The Hollywood Reporter's Angie Han described James's portrayal of the titular time traveler "dashing and a little sardonic" and highlighted his and co-star Rose Leslie's "inability to generate any real sparks between them". James played a series regular role in the second season of the satire series The White Lotus.
In 2024 he starred as Edward "Eddie" Horniman, Duke of Halstead, alongside Kaya Scodelario, Daniel Ings, and Ray Winstone, in the Guy Ritchie television series The Gentlemen, released on Netflix.
