Up (2009)
Cranky old widower Carl, escaping massive construction around his house, decides to fulfill his dead wife's dream of visiting far-off South America, so he ties a ton of balloons to his house and flies away, but accidentally brings along an annoying, chatty Boy Scout who hitches a ride on his porch.

Once on board the mothership, WALL-E encounters a bizarre group of robots and faces an evil ship's computer.
