The Englishman Who Went Up a Hill But Came Down a Mountain is a 1995 film released on 4th August, starring Hugh Grant. The film is based on a local legend of Taff's Well and nearby Garth Hill. Due to urbanisation, filming took place in Llanrhaeadr-ym-Mochnant and Llansilin in Mid Wales and is set in post World War I, 1917. Two English cartographers arrive at a village to measure its 'mountain', only to find that it can only be classified as a hill because it is just short of 1000 feet in height, which would have made it a mountain. The outraged villagers conspire to delay the cartographers' departure until an earth cairn is built on top of the hill to increase its height to over 1,000 feet.
