Fox's Steven Speilberg-produced "Terra Nova" has been one of the most buzzed about new shows for the last year or so, and finally we got a first glance at the TCA winter press tour. EW has a quick rundown of the trailer, which isn't available online yet, with the questions it presents.

"Terra Nova" is based in a apocalyptic future (2149) where a colony of humans jumps through a wormhole time-travel thing that takes them back 85 million years. They attempt to save humanity, and change the future, by taking steps millions of years before humans exist on Earth. And, there's dinosaurs that ATTACK! Hence, the giant machine guns, which I'm sure in no way could negatively effect humanity's future.
