There will be no second season of pre-historic drama Terra Nova on Fox. The network’s brass just made the decision after weeks of exploring potential Season 2 tweaks to the series set 85 million years in the past. Fox had to make the decision early so the show could make a fall return if renewed. Despite its pedigree, produced by Steven Spielberg and Peter Chernin, Terra Nova did not become a runaway hit, but its decent ratings, coupled with strong international sales for sibling 20th Century Fox TV, which produces the series, were keeping renewal hopes alive. 20th TV now plans to shop Terra Nova, starring Jason O’Mara and Stephen Lang, to other networks. At TCA in January, Fox’s entertainment president Kevin Reilly was non-committal when asked about the future of Terra Nova.
