“Game of Thrones” actress Sophie Turner will play “Frankenstein” author Mary Shelley in “Mary Shelley’s Monster,” Variety has confirmed.

She’ll star alongside Jeremy Irvine, who will portray husband Percy Shelley. “American Horror Story” star Taissa Farmiga will play Mary’s stepsister, Claire Clairmont.

“Mary Shelley’s Monster” is described as “the story of the most extraordinary 19th century teenage heroine told in a visceral, sexy, contemporary way,” according to producer Rose Ganguzza, who described the project to Deadline. “Our film is not a period drama. It is a story of youth that transcends time, a gothic romance, a love triangle that involves a dark passenger and we are tremendously excited to have such an exciting cast onboard this wonderful project.”

The film will follow Mary Shelley during the writing of her iconic novel, during which time she finds herself drawn into a “Faustian bargain with her own ‘monster’ of an alter ego” in the pursuit of literary success, according to Deadline.

The pic was penned by Deborah Baxtrom and will be directed by Coky Giedroyc. Ganguzza, Damon Lane, J. Todd Harris and Marc Marcum serve as producers. Turner is represented by CAA and Independent Talent Group, Irvine’s reps are CAA and Hatton McEwan, and Farmiga is represented through ICM Partners and Authentic Talent & Literary Management. Baxtrom is repped at ICM and Zero Gravity Management, while Giedroyc is represented by UTA and Independent.
