There will be a bit of a later start for J. Michael Straczynski's next project on the Showtime network as "Jeremiah" has been moved from its original January launch to either next March or June.

"The main premise is that there's a virus of some kind that gets loose more or less in present day and wipes out about two-thirds of the population -- anybody over the age of puberty," Straczynski recently told Sci-Fi Wire. "It targets hormones. Whoever has adult hormones gets nailed. It's now 15 years later, and the kids who survived the big death are now coming into their own. They've been riding, if you will, on the ashes of the old world, through clothes they'd grown into and food still incans. Now they're at a point where they can keep on declining and running out of things, or they can begin to rebuild the world. It's at the cusp of the rebuilding where our story takes place. So it's a story not about endings, but beginnings."

The series is set to star Malcolm Jamal-Warner and Luke Perry. Showtime has ordered 20 episodes of the new series.
