In science fiction, spaceships are often about more than transportation. The Millennium Falcon is as integral to the plot of Star Wars as the characters it shuttles from planet to planet. In Passengers, a new movie starring Jennifer Lawrence and Chris Pratt, the Avalon plays a similarly central role. The film is set entirely aboard the starship, which carries 5,000 hibernating passengers on a 120-year journey to a distant utopian planet called Homestead 2. Thirty years into the journey, two of those travelers, Lawrence and Pratt, accidentally wake up and are left to explore the massive spaceship on their own. That means the Avalon is far more than an elaborate backdrop.
