Marcella is a British "Nordic"-noir detective series, written, directed and produced by Swedish screenwriter Hans Rosenfeldt, creator of The Bridge. The series is produced by Buccaneer Media for ITV and distributed worldwide by Buccaneer's parent company Cineflix. It was first broadcast on ITV on 4 April 2016, with seven further episodes broadcast weekly.

The series stars Anna Friel as Marcella Backland, a former London detective who returns to work to investigate an open case from 11 years earlier involving an unidentified serial killer who appears to have become active again. Marcella also has to deal with a hectic home life, where her husband, Jason (Nicholas Pinnock), has made the decision to leave her and, at first, send their two children to a boarding school; but later on (in the second season) he uses Marcella's mental disorder as a means to take full custody. Nina Sosanya (series one), Ray Panthaki and Jamie Bamber are also credited as principal members of the cast.
