Tilda Swinton has slammed the Harry Potter movies for romanticising the "cruel" setting of boarding school.
In the books, written by J.K. Rowling, young wizard Harry, an orphan after his parents are killed by Lord Voldemort, is educated at Hogwarts School of Witchcraft and Wizardry.
Tilda herself is a boarding school alumni, having attended West Heath School where she was a classmate and friend of the late Princess Diana.
And in a new interview with The Scots magazine, Tilda admitted she isn't a fan of the magical films because she feels they convey a false image of how boarding school actually affects children.
“I think they (boarding schools) are a very cruel setting in which to grow up and I don’t feel children benefit from that type of education," Tilda told the publication. "Children need their parents. That’s why I dislike films like Harry Potter, which tend to romanticize such places."
Tilda's hatred of boarding schools encouraged her to found Scottish independent school Drumduan Upper School, near her home in Nairn, Scotland, in 2013.
The school offers "art based practical learning" as well as a boarding option for older pupils, and both her son Xavier and daughter Honor were educated there.
The 56-year-old actress also opened up to The Scots magazine about her decision to become an actress, which was mostly fuelled by her desire to step away from the life that had been "pre-ordained" for her by her family.
"I grew up under privileged circumstances and was expected to marry a duke," she added. "I spent a lot of time and energy making certain that I would not find myself living a life that had been pre-ordained for me."
Harry Potter author Rowling, an avid user of Twitter and frequent commentator on social issues, has yet to use the social media site to respond to Tilda's comments.
