Wallander is a British television series broadcast from 2008 to 2016. It was adapted from a Swedish series based on the Swedish novelist Henning Mankell's Kurt Wallander novels and starring Kenneth Branagh as the eponymous police inspector. It was the first time the Wallander novels had been adapted into an English-language production. Yellow Bird, a production company formed by Mankell, began negotiations with British companies to produce the adaptations in 2006. In 2007 Branagh met Mankell to discuss playing the role. Contracts were signed and work began on the films, adapted from the novels Sidetracked, Firewall and One Step Behind, in January 2008. Emmy-award-winning director Philip Martin was hired as lead director. Martin worked with cinematographer Anthony Dod Mantle to establish a visual style for the series.
