Fox cancels 'Terra Nova'

The prehistoric drama "Terra Nova" is history on Fox.

The network said this week it is dropping the pricey sci-fi series after a single season. The ambitious series, filmed in Australia with expensive special effects, got a lukewarm reception from viewers last fall despite high anticipation from sci-fi fans. It averaged less than 8 million viewers weekly.

The series followed a family on its journey back to prehistoric Earth on a mission to save the human race. It starred Jason O'Mara and Stephen Lang, with behind-the-scenes principals including Steven Spielberg.

"Terra Nova" was announced in May 2010, but production problems led to repeated delays in its debut.
