Mr Gompertz continued: “It’s good for us in two ways – from a financial point of view… to help maintain the building and the items in the house, but also the publicity – it generates an increased number of visitors once [the film’s] released.”

He said the director was very mindful that crews were careful when moving around the historical building.

Actor Elordi’s visit was a surprise to staff, though, he said.

“We didn’t know he was going to come here… the scenes weren’t going to involve Jacob Elordi, the monster, or the creature – I only saw when I watched ‘the making of’ footage that he was being interviewed in our Heaven Room, so he was here for a short time but they kept it very secret from us.”

He said “film tourism” was “big business” and hoped Frankenstein would bring more people to Burghley.

“I’m always very proud to see Burghley on the screen – it always looks great on any production we’ve had here,” he added.
