TV series based on the books, starring Georgina Sherrington and Felicity Jones as Mildred Hubble and Ethel Hallow respectively, was broadcast from 1998 to 2001. It was shot in Montreal, London and Cardiff. The series is mostly shot in studio in London, with some episodes filmed in Montreal, Quebec, Canada. The exteriors of Cackle's Academy used Castell Coch, a castle located near Cardiff. The courtyard was filmed at Loseley Park, near Guildford. Inside the school (Great Hall, classrooms etc.) was filmed at Twickenham Studios. Spin-offs When it was no longer realistic that Mildred would still be at school, the series relocated her to a magical university in Cambridge and was retitled Weirdsister College: The Further Adventures of the Worst Witch and saw the return of Felicity Jones as a reinvented Ethel Hallow. In 2004, a new series based on the 1998 series was made, entitled The New Worst Witch. It centred on the adventures of Mildred's equally bungling cousin, Henrietta "Hettie" Hubble, played by Alice Connor, also set at Cackle's Academy. Television series (2017–2020) A new version of The Worst Witch TV series began in 2017 airing on CBBC and concluded on April 20, 2020, this one starring Bella Ramsey as Mildred Hubble (replaced by Lydia Page in the fourth season so that Ramsey could focus on personal issues), Claire Higgins as Miss Cackle, and Raquel Cassidy as Miss Hardbroom. Stage adaptation (2018–2019) A musical stage production called The Worst Witch Live, adapted by Emma Reeves from Murphy's original books, was shown at the Royal & Derngate Theatre in Northampton from 27 November to 30 December 2018. In February 2019, the show began to tour the UK across 16 different venues. The Worst Witch Live by Kenny Wax Family Entertainment was shown at the Vaudeville Theatre in the West End from 24 July to 8 September 2019. This version is presented as a publicity play written by Mildred and acted out by the students and staff playing themselves, initially recreating Mildred's first year at school, although the second half takes on a metafictional angle as Agatha Cackle "infiltrates" the play and attempts to stage a coup of the magical government. The stage production received a 2020 Olivier Award for best family show.
