Sir Kenneth Branagh has led tributes to Swedish crime fiction author and Wallander creator Henning Mankell.
Belfast-born Branagh, who played Inspector Kurt Wallander in the British TV adaptations of Mankell's books, described the "passionate commitment" of the author who died in his sleep in Gothenburg, Sweden, aged 67.
The author had suffered from cancer, revealing his diagnosis in January 2014 in a newspaper column for The Guardian and a Swedish daily.
Branagh said: "In life and in art Henning Mankell was a man of passionate commitment. I will miss his provocative intelligence and his great personal generosity. Aside from his stringent political activism, and his decades of work in Africa, he also leaves an immense contribution to Scandanavian literature. His loving family, and those privileged to know him, together with readers from all over the world, will mourn a fine writer and a fine man."
The fourth series of the show, with Branagh returning to the lead role, is due to air on BBC One later this year.
Branagh added: "I always approach each series of Wallander with anticipation and excitement, but this last series of films contain some of the greatest challenges the character has ever faced."
He is survived by his wife Eva Bergman and his son, Jon Mankell.
