Sky renews 'Under Salt Marsh' for Season 2; Rafe Spall returns as action moves to Scotland

Sky has greenlit a second, as-yet-untitled season of 'Under Salt Marsh' — a straight-to-series order, meaning no pilot is shot first. Rafe Spall returns as Detective Eric Bull. The six-episode season relocates from the Welsh coast to a remote Scottish mining village, with filming set for 2027. Season 1 drew a 28-day audience of 2.5 million (Variety, 26 Aug 2026), Sky's biggest entertainment title of the year.
