Former "LOST" star Elizabeth Mitchell has joined J.J. Abrams and Eric Kripke's "Revolution" at NBC as a series regular, says The Hollywood Reporter. She joins a cast that includes Billy Burke ("The Twilight Saga"), Tracy Spiridakos, Anna Lise Phillips, Zak Orth, Graham Rogers, J.D. Pardo, Giancarlo Esposito, David Lyons, Maria Howell and Tim Guinee. Kripke, Abrams, Favreau and Bryan Burk ("LOST," Star Trek) serve as executive producers.

The show is described as follows:

Our entire way of life depends on electricity. So what would happen if it just stopped working? Well, one day, like a switch turned off, the world is suddenly thrust back into the dark ages. Planes fall from the sky, hospitals shut down, and communication is impossible. And without any modern technology, who can tell us why?

Now, 15 years later, life is back to what it once was long before the industrial revolution: families living in quiet cul-de-sacs, and when the sun goes down, the lanterns and candles are lit. Life is slower and sweeter. Or is it?

On the fringes of small farming communities, danger lurks. And a young woman's life is dramatically changed when a local militia arrives and kills her father, who mysteriously - and unbeknownst to her - had something to do with the blackout. This brutal encounter sets her and two unlikely companions off on a daring coming-of-age journey to find answers about the past in the hopes of reclaiming the future.

From director Jon Favreau ("Iron Man," "Iron Man 2") and the fertile imaginations of J.J. Abrams and Eric Kripke ("Supernatural"), comes a surprising "what if" action-adventure series, where an unlikely hero will lead the world out of the dark. Literally.
