These movies all focus on ordinary, everyday lives that have been interrupted by otherworldly forces: anything from voices beyond the grave, to sudden clairvoyant powers, to extraterrestrial visitors. As opposed to most sci-fi offerings, the emphasis here is on the "average Joe" and his entry into a fantastical, only-in-the-movies world of technological wonders, interstellar travel, lost civilizations, the future -- just about anything an enterprising team of filmmakers could dream up.
