Game Of Thrones’ star Natalie Dormer is heading Down Under for the highly anticipated TV version of Picnic At Hanging Rock.

The British star will play English headmistress Mrs Hester Appleyard in Foxtel’s six part re-imagining of Joan Lindsay’s classic, and she will be joined by French actress Lola Bessis (Swim Little Fish Swim) as Mademoiselle Dianne de Poitiers, mistress of French Conversation, Music and Dance.

As well as Dormer, there will also be plenty of other familiar faces amongst the teaching staff: Anna McGahan (The Doctor Blake Mysteries) will play geography and maths teacher Miss Greta McCraw, Orange Is The New Black star Yael Stone has been cast as Miss Dora Lumley, mistress of Deportment and Bible Studies, while Sibylla Budd (Winners & Losers) is the head of art and literature Mrs Valange.

The roles of the students at Appleyard College for Young Ladies will be played young stars such as Lily Sullivan (Camp), Madeleine Madden (Tomorrow When The War Began), Samara Weaving (The Babysitter) and Ruby Rees (Miss Fisher’s Murder Mysteries).

Picnic at Hanging Rock tells the story of the mysterious disappearances of three schoolgirls and one teacher on Valentine’s Day 1900, with filming to begin in Victoria later this month.

Penny Win, Foxtel’s head of drama, says: ““Though the story remains in 1900, Picnic at Hanging Rock will be 21st century storytelling for the premium Foxtel drama audience.”
