CNET turns to science fiction for a glimpse into the bedrooms of tomorrow.

Cryosleep factors into loads of movies, from Alien to Avatar, from 2001: A Space Odyssey to Event Horizon. The defrosting scene is a sci-fi staple, as bleary-eyed travelers awake from glass cases and re-examine their surroundings. That’s handy for filmmakers, because as well as offering a plausible method of space travel, it gives the audience useful exposition when disoriented characters ask questions like “How long have I been out?”
