In TNT's alien-invasion drama Falling Skies, due next summer, Noah Wyle stars as the de facto resistance leader against aliens who invaded Earth. The producers insist the drama will focus on what the aliens left behind rather than the invasion itself, although you wouldn't get that from the first trailer.
The series from Steven Spielberg seems to draw not only from his own War of the Worlds remake — an adaptation of the H.G. Wells novel — but from many sci-fi facets, including Battlestar Galactica (with cylon-looking drones) and V (with the idea of joining a resistance).
