With Revolution, NBC is clearly hoping "gone" does not equal "forgotten."

The NBC sci-fi adventure, fall's most popular new series among youngerviewers, is in the midst of a four-month break that started November 26and will stretch to the end of March. It's a risk -- but producer J.J.Abrams, who went through a similar break in Lost, says he's happy to take it.

The advantage, says Abrams, is that when Revolution returns, it can run straight through without further breaks or repeats. Doing that with Lost, he says, "just helped enormously. So when the idea came up, I was just enormously relieved."

Producer Eric Kripke says there was another, creative advantage for theshow, which is set in a sword-swinging, horse-riding world withoutelectricity. Taking some time off allowed the writers to catch theirbreath and figure out what went right - and wrong.

"I felt likewe could pick up the pace of the stunning revelations. I thought maybethe pace of the shocking surprises was a little too slow ... We wanted tohave a second half that was bigger and better and more exciting."

The show's story will pick up right where it left off, says Kripke, butas the season goes on, it will also explore more of the world beyondthe war-torn Monroe Republic. So if you've wondered why these peoplehaven't rediscovered pre-electricity technologies like steam engines andsewing machines, just wait. You'll be visiting other countries wherethose machines are thriving.

But don't worry; the break isn'tchanging the central focus of the show. It will at heart, says Kripke,continue to be a family show: "The Waltons with swords." And,says Abrams, the show's fictional world will continue to struggle alongwithout most modern conveniences, for this season and, he hopes, formany seasons to come.
