Original series was picked up for a 13-episode second season

It doesn't take a genius to keep a good thing going, and the folks at the Sci Fi Channel are no fools when it comes to their popular show "Eureka."

The original series about a secret town full of geniuses has been picked up for its second season, producing 13 more episodes chock full of brainy goodness.

Set in the titular small town hidden by the U.S. government, "Eureka" revolves around the hyper-intelligent residents who live in environment that nurtures brilliant thinking, the next big invention and state-of-the-art education and healthcare. But just because great minds are gathered together, doesn't mean they think alike. Like any small town, the denizens have their share of problems, exacerbated by their odd circumstances. Jack Carter (Colin Ferguson) is the everyman U.S. marshal who stumbles upon the secret government research facility after separating from his wife.

Stars reprising their roles for the second season include Ferguson, Salli Richardson-Whitfield, Joe Morton, Jordan Hinson, Ed Quinn, Debrah Farentino and Matt Frewer.

"Eureka's" two-hour premiere on July 18 drew more than 4 million viewers, making it the most-watched episode of an original series in the channel's history. About 1.7 million of those viewers were in the key adults 18-49 demographic, and 1.9 million fell in the 25-54 age range.

The first season concluded this past Tuesday, Oct. 3 and beat out The CW's premiere of "Veronica Mars" in the key male 18-49 and 25-54 demos. Overall, the show is a consistent Top 10 cable finisher for Tuesday nights and has been a Top 5 program for nine weeks out of its 12-week run.

"Eureka's" second season will begin production in Vancouver this spring, so it can return next summer.
