Prime Video is developing a television adaptation of Swedish author Ulf Kvensler's debut novel into a four-episode psychological thriller titled Sarek. The drama features actors Felix Sandman, Kitt Walker Johansson, Alva Bratt, and Nora Rios in a story centred on a hiking expedition through Sweden's Sarek National Park that descends into psychological manipulation and violence, with surviving witnesses offering contradictory accounts of the events.

The series is currently in pre-production with principal photography commencing in July, targeting a 2027 release exclusively on Prime Video's Nordic streaming service. Production is being handled by Banijay Entertainment's Jarowskij and Yellow Bird divisions in collaboration with Amazon MGM Studios, with creative direction from Måns Herngren.
