Eva Green and Josh Hartnett have been cast in the upcoming Showtime horror drama series Penny Dreadful.

The actors will take on the lead roles in the drama from three-time Oscar nominee John Logan, according to The Hollywood Reporter.

Penny Dreadful was created by Logan (Hugo, The Aviator, Gladiator), who will write and executive produce alongside Sam Mendes and Pippa Harris (Revolutionary Road).

The "psycho-sexual horror series" will see Harnett play Ethan, a charming and brash man who isn't afraid of violence, while Green will play Vanessa, an "enigmatic heroine with haunted eyes".

Production on the show will begin this October in London and is scheduled to air in spring 2014.
