Warwick Davis returns to cast his magic in new Harry Potter TV series

'All aboard the Hogwarts Express', again!

Actor Warwick Davis will return to the world of witchcraft and wizardry for the new Harry Potter series.

That's according to HBO, the company that is making the show.

The Bafta-winning actor is set to star as Professor Filius Flitwick, the teacher he played in the original Harry Potter films.

He is the first actor from the film franchise to step back into character for the new TV series.

Arabella Stanton, Dominic McLaughlin and Alastair Stout were announced earlier this year as the young actors who will play the leading three characters in the new series

However, another actor will take over Warwick Davis' other character Griphook, a goblin employed at the Gringotts Wizarding Bank.

Leigh Gill will take on the role, who played Red in Fantastic Beasts and Where to Find Them.

As part of the annual Back to Hogwarts celebration on 1 September, when fans mark the day students return to the witchcraft and wizardry boarding school, new cast members for the Potter TV series were announced.

New recruit Elijah Oshin will play Harry Potter's friend Dean Thomas.

Finn Stephens and William Nash are Vincent Crabbe and Gregory Goyle, the sidekicks to Harry's main rival, Draco Malfoy.

The TV series will take about 10 years to complete, with the first episodes expected to come out in 2027.

How will the TV series be different to the films?

All eight Harry Potter films were shot at Warner Bros Studios Leavesden in Hertfordshire.

The new TV series will be made at the same place, but it's expected to look and feel a bit different.

HBO has previously said the series would be "a faithful adaptation of the iconic books".

The TV series will have more opportunities to explore the plots of the books, as they have more time than the films did.
