Hollywood hottie Josh Hartnett softens the scariness though as he leads the cast as American sharp shooter Ethan Chandler.
It's Victorian London and the police are investigating a series of gruesome murders, but renowned explorer Sir Malcolm Murray (Timothy Dalton) and the strangely beautiful Vanessa Ives (Eva Green) know there's something darker at play.
Can Ethan, and Dr Frankenstein, help them discover what? Billie Piper and Rory Kinnear also star in the chillingly gripping drama.
