Lena Headey has joined the cast of the adaptation of Jacqueline Ess: Her Will and Testament.
According to Variety, Headey will take on the title role of Jacqueline Ess, as Clive Barker's short story is given the big screen treatment.
The film will follow the title character, who discovers that she can transform people's bodies with her mind.
Jovanka Vuckovic will make her feature film directorial debut with the film, while Barker himself is also on board as an executive producer.
Headey can currently be seen reprising her role as Cersei Lannister in the fourth series of hit show Game of Thrones.
300: Rise of an Empire was the last time we saw her on the big screen, but she has also completed work on Zipper.
Zipper sees her team up with Dianna Agron and Patrick Wilson, while Mora Stephens is in the director's chair.
Headey is also set to reprise the role of Jocelyn Fray in The Mortal Instruments: City of Ashes.
