Extended Revolution Trailer: Out of the Darkness...

It's happening, isn't it?

So asks Elizabeth Mitchell's character in the following extended trailer for Revolution, the upcoming NBC drama that focuses on a world without electricity.

Premiering September 17, the series is produced by J.J. Abrams and the pilot directed by Jon Favreau. Not a shabby resume, huh?

It stars Tracy Spiridakos as Charlie Matheson - a young woman intent on saving her family from a warlord (Giancarlo Esposito) who is after information about the global blackout - and Billy Burke as a relative of Charlie who appears to know more than he initially lets on. He's also really good with a sword.

Watch the promo now and sound off: Will you give Revolution a shot?
