Steven Spielberg's 'Terra Nova' to Air Two-Hour Sneak Peek in May

Fox fires show’s writers -- with intention of hiring them back in the spring once production resumes -- to save money on the $4-million-an-episode price tag.

Steven Spielberg's big-budget time travel drama, Terra Nova, will air a sneak peek in May 2011, Fox confirmed to the New York Post.

The series won't kick off until the fall. Glee used the same tactic last year to create buzz.

The two-hour episode will introduce viewers to the show, which chronicles a family living on the nearly-destroyed Earth in 2149. They travel back to prehistoric times to try to save the planet by curbing scientific experimentation and out-of-control population growth.

Spielberg is an executive producer, and sources tell the Post he's very hands-on, signing off on the script, cast and special effects. His DreamWorks is also one of the production companies behind it.

In order to save money until the first episode -- which is rumored to have cost $14 million -- airs, Fox recently fired a number of the show's writers, with plans to rehire them in the spring when production gets underway again.

Each hourlong episode reportedly costs $4 million, according to the Post.
