Billie's most recent role is as Brona Croft in the hit series Penny Dreadful which has just returned to Showtime (US) and Sky Atlantic (UK) for its highly anticipated second series. The psychological thriller - executive produced by James Bond director Sam Mendes - unites a host of literature's most famous terrifying characters, including Doctor Frankenstein and Dorian Gray, alongside Billie's portrayal of an Irish immigrant who moved to Victorian London to escape her dark and sordid past. And blimey, is it sordid! Don't be fooled by her beautiful appearance, however, because she's actually riddled with tuberculosis. That didn't stop her from getting up to all kinds of shenanigans - *ahem* - throughout Season 1, though, as she formed an intimate relationship with Ethan Chandler (Josh Hartnett) and accepted a naked modelling job. Whatever tickles your pickle.
