Magic and maths 'Mini-school' and tutors set up for Harry Potter stars

Harry Potter may have been overjoyed at going to Hogwarts school of witchcraft and wizardry, but the children playing Harry, Ron and Hermione in the forthcoming TV series will see their own schools vanish for the rest of their childhoods.

The child actors – along with those playing Draco Malfoy, Ginny Weasley and the other Hogwarts pupils – will get much of their education from tutors at a "mini-school" to be conjured up at Warner Brothers' Leavesden studios in Watford, when filming for HBO's production starts later this year.

HBO's chief executive, Casey Bloys, says the project will run for "10 consecutive years", meaning the actors now aged between 9 and 11 will be spending their school years fitting in lessons and revision between learning lines and putting on makeup.

Jo Austin of Tayberry Tuition, which has supplied specialist on-set tutors for Netflix and BBC productions such as The Crown, said: "This Harry Potter series is fairly unique in that it is child-based, the children are the stars and they are going to be on screen all the time.

"I can't imagine many days filming when you haven't got any children on set, so I think they are going to be in there most of the time and working very hard. They will be out of school for a period of six to nine months to film and complete each series."
