More used to being scared than generating terror on Game Of Thrones (she did nearly marry Joffrey, don’t forget), Sophie Turner has signed on to star alongside Jeremy Irvine and Taissa Farmiga in Mary Shelley’s Monster.

Coky Giedroyc, who has had a thorough grounding in gothic horror working on episodes of Penny Dreadful, will direct the tale about Shelley creation of the seminal horror tale Frankenstein while struggling with her own alter-ego and tempestuous relationship with Percy Bysshe Shelley (Irvine). Farmiga is aboard as her stepsister, Claire Clairmont, who may or may not have had an affair with Shelley but who was definitely bonking Byron.

According to producer Rose Fanguzza, this will be a different take on the Shelley story. “Our film is not a period drama,” she tells Deadline. “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 on board this wonderful project.”

This will need to distinguish itself, because there’s already at least one Mary Shelley film in development: Elle Fanning signed up last month to play her in A Storm In The Stars.
