The Iron Giant
Maine, 1957. Young Hogarth Hughes discovers a colossal robot that fell from space, its memory wiped, hiding in the woods behind his house. As Hogarth teaches the Giant about the world — and about choice — a paranoid government agent closes in, convinced the visitor is a Cold War weapon that must be destroyed before it destroys them first.
Tomorrowland
Optimistic teenager Casey Newton receives a mysterious pin that, when touched, drops her into a vision of Tomorrowland — a gleaming hidden city of impossible future technology. Tracking down the pin's origin leads her to Frank Walker, a disillusioned former boy-genius who was exiled from that city decades ago, and together they race to understand why humanity's brightest possible future has been sealed away and left to die.
