won the role in May 2014, and later reported that Marvel had considered him for it since 2012. Production on the first season began in Summer 2014, and it premiered on Netflix in April 2015. It ran for three seasons and was produced over four years, concluding in late 2018. In the following years, Cox shared his interest in reprising the role in a future project, also noting his contractual obligations by Marvel Studios to do so. Between filming seasons of Daredevil, Cox made his New York theater debut, co-starring in the off-Broadway production of Incognito at the Manhattan Theatre Club. In late 2017 it was announced that he had joined the cast of Stripped, a thriller produced by Lorenzo di Bonaventura, who also produced Cox's breakout film Stardust, but it was never produced. He also acted opposite Michael Caine, Jim Broadbent, Ray Winstone, and others in the 2018 film King of Thieves, based on the true story of the 2015 Hatton Garden jewelry heist in London; it reunited him with James Marsh, who directed him in 2014's The Theory of Everything. New projects and return to Daredevil (2019–present) After Daredevil abruptly ended, Cox took the opportunity to star opposite Tom Hiddleston and Zawe Ashton in the West End production of Harold Pinter's Betrayal, which opened on 14 March 2019 and closed on 8 June. Cox was sought for the role by director Jaime Lloyd, who had previously directed him in the 2008 production of the Pinter play The Lover and The Collection. Betrayal transferred to Broadway with the original cast for a 17-week limited engagement, beginning previews on 14 August and closing on 8 December 2019. During this period, Cox also took part in some of his friends' projects; in late 2018 he acted in the short film The Knot, directed by Daredevil and The Defenders script supervisor Rebecca Schwab, and in a 2019 episode of Daredevil costar Deborah Ann Woll's Dungeons & Dragons internet show Relics and Rarities. In Fall 2020, Cox began filming the RTÉ Dublin crime series Kin, in which he stars with Aiden Gillen, Clare Dunne, Maria Doyle Kennedy, Ciarán Hinds, and Emmett Scanlan. The eight-part series was released on 9 September 2021, on AMC+ in the US and Canada, and on 12 September 2021, on RTE in Ireland. In December 2021, Marvel Studios president Kevin Feige confirmed that Cox would be reprising the role
