Downton Abbey star Jessica Brown Findlay has signed on to play the female lead in 20th Century Fox's Frankenstein reboot.

Daniel Radcliffe is starring as Igor with James McAvoy playing Dr. Victor Frankenstein in this revisionist version that tells Mary Shelley's classic story from Igor's perspective. Jessica Brown Findlay stars as a trapeze artist who becomes close to Igor after he saved her life. Here's what Daniel Radcliffe had to say about the story at the Toronto International Film Festival this week.

"It's about two young, brilliant guys pushing each other. Eventually one loses his morality and the other has to bring him back."

Paul McGuigan (Push, Lucky Number Slevin) is directing from a screenplay by Max Landis (Chronicle). Production is scheduled to begin sometime this fall in London.

Aside from playing Lady Sybil on Downton Abbey, Jessica Brown Findlay also starred in the 2011 U.K. drama Albatross, and she will next be seen on the big screen in Warner Bros.' Winter's Tale.
