The film, which stars Colin Firth and Julie Walters, is due for release in summer 2019 and filming has taken place at several Yorkshire locations.
The novel, written by Frances Hodgson Burnett and published in 1911, is set in the North York Moors, where the main character Mary Lennox's uncle, Archibald Craven, owns a brooding mansion called Misselthwaite Manor.
Scenes that take place in the secret walled garden - which in the story is locked by Mr Craven after his wife's death in an accident - were shot at Helmsley Walled Garden, a five-acre garden beneath the ruins of Helmsley Castle.
The 450-acre Duncombe Park estate and house were used to stand in for the fictional Misselthwaite Manor.
The setting of the film has been moved forward to 1947 for the new adaptation, rather than the Edwardian period in which the novel is set.
The Secret Garden tells the story of orphan Mary Lennox, a 10-year-old whose parents died in a cholera epidemic when the family were living in British India. She is sent to her uncle, and gradually learns about the garden while recovering her health, becoming determined to find her way inside.
Helmsley Walled Garden
The five-acre garden was laid out in 1756, after the Duncombe family had built Duncombe Park nearby. It has now been restored as a working kitchen garden. The castle originally had its own walled garden along the banks of the river to the south. The current garden has glasshouses which date from 1850.
This impressive medieval fortress was built in stone in the 13th century and has passed through the hands of several noble families - it was once owned by King Richard III. It was besieged during the Civil War and much of the site was destroyed, although the mansion was spared. The Duncombe family's association with the castle began in 1695, when banker and politician Charles Duncombein bought the estate. His sister and her husband later inherited it and their son changed the family name to Duncombe. The family commissioned the building of Duncombe Park, with the intention of the castle acting as a picturesque backdrop to their country house. The castle is now owned by English Heritage.
The family seat of the Duncombe family, who use the title Barons Feversham. The house has not been open to the public since 2011, although visitors can tour the gardens. The estate featured as Groby Park in the 2012 TV adaptation of Parade's End. It was used as a World War One hospital and then leased to a girls' school in the 1920s while the family lived in a property nearby until 1985, when they moved back into their ancestral home.
