You're gonna have to wait a little longer for your TV dinosaurs: Fox just announced that it's pushing the premiere of Steven Spielberg's big dino-drama Terra Nova. The show had been set to debut this winter, but today the network said it won't be ready until May. And even then, we'll only get to see the pilot episode, since the actual series premiere of Nova — which stars Jason O'Mara (Life on Mars) as a dude who takes his family back in time in order to save the Earth — won't be until fall 2011. It's the same scheduling strategy the network used to launch Glee, so maybe it'll all work out. Plus, it means we'll have more time to think up Land of the Lost jokes.
