Collateral is a four-part British television drama serial, written and created by David Hare, and directed by S. J. Clarkson.^[1] It was first broadcast on BBC Two on 12 February 2018.

The series, described by Hare as "a police procedural without any of that police attitudinising",^[2] stars Carey Mulligan as DI Kip Glaspie, assigned to investigate the shooting of a pizza delivery driver in inner city south London. The ensuing story explores a complex web of characters who are all somehow connected with the story. Nathaniel Martello-White stars as Glaspie's partner, DS Nathan Bilk. Jeany Spark, Nicola Walker, John Simm and Billie Piper are also credited as principal members of the cast.^[3]

The series was Hare's first original series for television, despite having written for the BBC since 1973.^[4] Piers Wenger, the BBC's head of drama, described the series as "a contemporary and thought-provoking state-of-the-nation thriller that pushes the boundaries of what audiences expect^[5]

The show was produced by The Forge and distributed worldwide by All3Media, which brought Netflix on board to co-produce the series and release it internationally on 9 March 2018.^[6][7] Dazzler Media released a DVD of the series on 26 March 2018.^[8]
