Production has now started on the new hotly anticipated Harry Potter TV series, with further casting announced.

Filming of the new HBO TV show version of the popular fantasy novel series is taking place at Warner Bros Studios Leavesden in England.

HBO announced on Monday that further casting has also taken place, with young actor Rory Wilmot playing Harry’s schoolfriend Neville Longbottom and Amos Kitson taking on the role of his cousin Dudley Dursley.

Meanwhile, Sherlock actress Louise Brealey is to play Hogwarts Quidditch coach Madam Rolanda Hooch, and Game Of Thrones star Anton Lesser will be wandmaker Garrick Ollivander.

Each season of the show will be a faithful adaptation of the Harry Potter books, from author and executive producer JK Rowling.

It follows the popular film adaptations that starred Daniel Radcliffe, Emma Watson and Rupert Grint as the protagonists.

Other stars who have previously been announced include award-winning US actor John Lithgow as Hogwarts headmaster Professor Albus Dumbledore, Welsh comedian and actor Paul Whitehouse as Hogwarts caretaker Argus Filch, and Rivals actress Katherine Parkinson as Molly Weasley.

The series is set to hit TV screens in 2027 on HBO and HBO Max.
