She's been filmed at some of the world's most exotic locations - but it seems rural Norfolk still holds an attraction for Keira Knightley.

The Hollywood star was at a remote farmland location near Docking on Thursday to record scenes for her latest project, the sci-fi thriller Never Let Me Go.

The day before, cast and crew were on the expansive sands of Holkham beach - already famed on the silver screen thanks to Gwyneth Paltrow's memorable final scene from Shakespeare in Love.

It is also a stone's throw from Holkham Hall, where Knightley made her previous Norfolk appearance in front of the lens for period drama The Duchess, filmed in October 2007.

Holkham's hall administrator Mike Daley said he welcomed the return of the Atonement and Pirates of the Caribbean star.

"I think the crews come back here because we treat them so well," he said.

"It is a buzz when they are on the beach, but perhaps not when they are here in the hall. It is not all glamour - these people work extremely hard and when they are in the house we have to work the same hours. But it is very interesting to see it."

After moving inland to their new location, the stars were not on the set on Thursday lunchtime while cameras and props were readied for a scene on a country track shaded by a characteristic tree - which could become as recognisable as the actors.

Location manager Josh Yudkin said: "Wait until you see the film - this is going to be a famous tree.

"Some of the film is set in Norfolk and it has been a great experience so far. Things are going good and Norfolk is looking after us well."

Never Let Me Go is an adaptation of Kazuo Ishiguro's novel, with Knightley starring alongside Carey Mulligan and Andrew Garfield.

The three characters grow up together in an isolated boarding school, only to discover they have been bred as clones to be used for organ donation.

The screenplay is by Alex Garland, the writer behind horror classic 28 Days Later, and the film is directed by Mark Romanek.

Producer Allon Reich said: "We have had a wonderful time filming in Norfolk. It is full of places of outstanding natural beauty, which we hope will help lend an epic quality to our film."
