Foxtel — an Australian pay television company — has revealed it has cast for a number of roles for “Picnic at Hanging Rock,” a 21st century re-imagining of Joan Lindsay’s classic, which arguably might be best known for Peter Weir’s 1975 film adaptation. An integral role in the production has been filled by “Game of Thrones” star Natalie Dormer who will play English headmistress Mrs. Hester Appleyard.

Joan Lindsay’s highly regarded literary piece was published in 1967, and tells the story of the disappearance of three schoolgirls and their governess on Valentine’s Day 1900 and the sprawling consequences that resulted. The series will be adapted by Larysa Kondracki (“Legion”) and Michael Rymer (“Hannibal”) with Amanda Brotchie attached to direct.

In addition to Dormer, a litany of other characters have been cast including Lola Bessis (Mademoiselle Dianne de Poitiers), Anna McGahan (Miss Greta McCraw), Yael Stone (Miss Dora Lumley) and Sibylla Budd (Mrs Valange) who will play teachers of Appleyard College for Young Ladies. Students of the college will include Ruby Rees (Edith Horton), Madeleine Madden (Marion Quade), Samara Weaving (Irma Leopold), Lily Sullivan (Miranda Reid) and debuting Inez Curro (Sara Waybourne).

“Picnic at Hanging Rock” is set to debut on Foxtel’s showcase channel in Australia this year, however a specific date is yet to be announced. As for a stateside bow, no word yet. [Deadline]
