Owners of historic buildings used in likes of Bridgerton warned of potential damage to possessions and reputations

When the owner of Drayton House in Northamptonshire was approached to allow his 127-room mansion to be the location of a film called Saltburn, it was “100%” the generous fee on offer that swayed his decision, he said, adding: “These houses don’t run on water.”

But there were unintended consequences of Charles Stopford Sackville’s decision after the movie’s release last year. The popularity of Emerald Fennell’s class satire led to a rush of selfie-taking trespassers after TikTok videos giving directions to the estate went viral.
