Revealing mistake: In the first scene, young people are removing scrap from a rooftop. The camera angle changes to look over the rescue team and back at the roof. In the distance, visible in the upper left of the screen, a Canadian flag is waving in the breeze. Also a short while later the camera looks back over the team away from the children, and the CN Tower appears to be in the background. Like many TV shows, Falling Skies was filmed in Canada, but the events are supposed to take place in Massachusetts, USA. (00:00:25 - 00:02:00)
