We just got an extended look at the anticipated TNT sci-fi drama Falling Skies from Steven Spielberg by way of a new featurette/trailer, and today the marketing machine keeps on running. Three brand new promo posters have just cropped up with some pretty cool imagery. One is reminiscent of one of the posters for District 9, another has a strange glowing spine, but my favorite has a great contrasting image of a child's paper airplane with the invading alien ships and an ominous tagline.Check out these cool posters and the series synopsis after the jump.Click over to AICN to see another poster for Falling Skies.Here's the official synopsis for Falling Skies:

After an all-out invasion of the planet by an alien military force, ordinary people must do extraordinary things to survive in TNT’s powerful new drama series from DreamWorks Television and executive producer Steven Spielberg, starring Noah Wyle. FALLING SKIES opens in the chaotic aftermath of an alien attack that has left most of the world completely incapacitated. In the six months since the initial invasion, the few survivors have banded together outside major cities to begin the difficult task of fighting back. The series combines stunning visual effects and personal human stories about triumph and survival in the most devastating circumstances.
