Revolution - Season 1 - Elizabeth Mitchell interview

Now, more than two years after that feverishly dissected drama wrapped, the actress is clearly thrilled to be starring in another big-budget, high-concept mystery from executive producer J.J. Abrams. "They're my favorite because they're so romantic in the way that I like to be romantic," she says. "Things are lush and amazing, and it just feels like there's an element of anything can happen. That's my favorite stuff to do."

Thankfully, there will be more for the actress—who appeared only briefly in the pilot via flashbacks—to do starting tonight. (C'mon, you didn't really think Abrams and Revolution creator Eric Kripke would hire EMitch for a role that wasn't major, did you?) Look for a pivotal sequence that takes place shortly after the blackout occurred 15 years ago in which Rachel and hubby Ben (Tim Guinee) decide to pack up kids Charlie and Danny and hit the road. First pit stop: Ben's lab, where the plugged-in scientist picks up a few things. (Hmmm...might those things hold clues to what caused the world's power to go out? And perhaps shed light on how to turn it back on?) Along the way, they run into a drifter who threatens the Matheson-family food supply. "My character has a huge split-second decision to make," reveals Mitchell, "and it's gonna be interesting to see which way she goes on it."
