Sophie Turner is to play the title role in 'Mary Shelley's Monster', a new biopic of 'Frankenstein' author Mary Shelley.

The 18-year-old 'Game of Thrones' actress will appear in the film alongside 'War Horse' star Jeremy Irvine, who will play the poet Percy Shelley, her on-screen lover and eventual husband.

Producer Rose Ganguzza says 'Mary Shelley's Monster' will tell the story of ''the most extraordinary 19th century teenage heroine told in a visceral, sexy, contemporary way''.

She told Deadline.com: ''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 flick will also feature Taissa Farmiga, star of 'Higher Ground', while directing responsibilities have been handed to Coky Giedroyc, who is best known for her work with TV dramas, such as 'Wuthering Heights' and 'The Virgin Queen'.

In addition to Rose Ganguzza, the film will be produced by J Todd Harris, Damon Lane and Marc Marcum.

Filming is set to begin later this year in the UK and Malta, although a release date is still to be announced.
