My thoughts went to the combination of being on a long flight from Earth to another world, through the vast, isolating interstellar distance. These people will either need to live and breed for generations aboard those ships, or sleep the whole way.<\/p>\n<p>\u201cI went with the notion of sleeper ships, and the possibility of someone waking early and having no way back to sleep. Once I had that idea, and it really sank its claws into my imagination, it gave rise almost inevitably to the chain of events that became the plot of the film.<\/p>\n<p>\u201cFirst he tries to go back to sleep. Then he tries to call for help. Failing all of that, he tries to make a life alone, but begins to go mad in isolation. \u2026 The places where it led him seemed inevitable, and it became a love story. A love story haunted by tough philosophical questions and ethical quandaries. That fascinated me.\u201d<\/p>\n<p><iframe title=\"Passengers | Creating Sets of Starship Avalon (2016)\" src=\"https:\/\/www.youtube.com\/embed\/nCNz1sM1Vqk?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen=\"\" data-ratio=\"0.5625\" data-width=\"800\" data-height=\"450\" style=\"display: block; margin: 0px; width: 800px; height: 450px;\"><\/iframe><\/p>\n<p><strong>GeekWire: How much did you have to delve into the physics of all this? I\u2019m sure there will be space geeks who will be looking at every angle of this for scientific missteps.<\/strong><\/p>\n<p><strong>Jon Spaihts:<\/strong> \u201cI did do specific research into technical aspects of this starship and where it might be going, what it might see along the way. There are reasons why the movie doesn\u2019t offer a date when these events are unfolding, or specifically name the star that they\u2019re heading to. That\u2019s because I wanted a little poetic license, and moreover, to dodge fussy calculations of how long these movements would take. Ultimately, you want the focus to be on the characters\u2019 story.<\/p>\n<p>\u201cThat said, throughout the production, I was a kind of guardian angel of rigorous science. Sometimes I succeeded, and sometimes I failed. You win some arguments, you lose some arguments, but on the whole, I think we did reasonably well.\u201d<\/p>\n<p><strong>Q: There was one reference to a star that the spaceship was making a slingshot maneuver around&nbsp;\u2013 Arcturus, I think? Filmgoers might be thinking to themselves, \u2018Now, how far away is that?\u2019<\/strong><\/p>\n<p><strong>A:<\/strong>&nbsp;\u201cIt\u2019s about the right distance away. [36.7 light-years from Earth.] I think the dodgiest thing about the slingshot maneuver is, I don\u2019t know how much velocity you can steal from a body you\u2019re passing that does not have substantial proper motion with respect to a transit perpendicular to your direction of travel.<\/p>\n<p>\u201cIf it\u2019s pretty stationary with respect to you, I don\u2019t think you can steal a lot of velocity from it, especially if you\u2019re traveling 0.5 c before you get there. So it\u2019s more of a showy move. It might be a way of changing your trajectory.\u201d<\/p>\n<p><strong>Q: Anything you want to say about the propulsion system you use to get to half of the speed of light?<\/strong><\/p>\n<p><strong>A:<\/strong> \u201cThe fusion reactors are at the heart of the ship, and there\u2019s an ion drive at the tail. It\u2019s obviously a constant-thrust ship, because the engine\u2019s always on. That means that the spiraling blades of the ship need to be conical sections to compensate for the thrust of the jet, and make down feel like \u2018down\u2019 inside the spaceship.<\/p>\n<p>\u201cThe ship has to rotate about once every 80 seconds to produce 1 G, and because there\u2019s no propellant tank on board, you have to be harvesting hydrogen from the near-vacuum of space with that front shield and funneling it back into the ship in order to keep the fusion reactor running and supply propellant to the ion drive.\u201d<\/p>\n<p><strong>Q: Wow, I did not catch that fuel-harvesting function&nbsp;\u2026<\/strong><\/p>\n<p><strong>A:<\/strong> \u201cYeah, that magnetic screen at the front of the ship is actually spreading very wide wings in the space ahead of them and funneling trace gases into the ship.\u201d<\/p>\n<p><strong>Q: Anything else that space geeks should watch for in the movie?<\/strong><\/p>\n<p><strong>A:<\/strong> \u201cOn the whole, we\u2019re in pretty good shape. We\u2019re definitely following a funny convention that was initiated by \u2018Gravity\u2019 and perpetuated by&nbsp;\u2018The Martian,\u2019 where spacewalkers have extra-long tethers. The nature of our tether system makes that semi-believable, but it\u2019s still a very long tether.<\/p>\n<p>\u201cWe\u2019re approximately right in terms of the physics of a rotating spaceship. There are some niceties of Coriolus force and the transition from 1 G to zero G that maybe we\u2019re playing a little fast and loose with on the screen, but some of that is just about the possibilities of production.\u201d<\/p>\n<p>[The film\u2019s director, Morten Tyldum, told GeekWire that the biggest special-effects scene, involving a swimming pool that suddenly goes into zero-G, required months&nbsp;of research into how a body of water would respond to changes in the Coriolus force. It also required lots of exhausting work by Jennifer Lawrence, who was pinned down in a pool to film the CGI-enhanced scene. \u201cThat is a unique scene,\u201d Tyldum said. \u201cIt\u2019s fun to do something that\u2019s never been done before.\u201d]<\/p>\n<p><iframe loading=\"lazy\" title=\"PASSENGERS - Gravity Loss Scene\" src=\"https:\/\/www.youtube.com\/embed\/IOVrvZ3aKt4?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen=\"\" data-ratio=\"0.5625\" data-width=\"800\" data-height=\"450\" style=\"display: block; margin: 0px; width: 800px; height: 450px;\"><\/iframe><\/p>\n<p><strong>Q: Any influences from other works of science fiction?<\/strong><\/p>\n<p><strong>A:<\/strong> \u201cWell, \u20182001\u2019 and Tarkovsky\u2019s \u2018Solaris\u2019 are undoubted influences. There\u2019s so much fiction that it\u2019s hard to break it all down.\u201d<\/p>\n<p><strong>Q: You must be having a ball creating these mythos movies, like \u201cPrometheus\u201d and \u201cDoctor Strange.\u201d What gives you the most joy, and what\u2019s the biggest challenge about creating these stories?<\/strong><\/p>\n<p><strong>A:<\/strong> \u201cThe joy is getting to participate in the fictional canon. That\u2019s been inspirational for me for years. I\u2019ve been a legitimate and earnest fan of those fictional worlds, and for me to get to play in that sandbox, and play with those characters \u2013&nbsp;that\u2019s incredible. I have nothing to do with the new \u2018Alien\u2019 movie that\u2019s coming out, but a character I invented is in it, and that\u2019s pretty amazing.\u201d<\/p>\n<p><strong>Q: And the biggest challenge? The challenge is probably the flip side, that you have to be respectful of the canon.<\/strong><\/p>\n<p><strong>A:<\/strong>&nbsp;\u201cIn both of those cases, actually, this is true. The canon is gigantic. Doctor Strange is chronicled across hundreds of comic books, and guest appearances in hundreds of other comic books. It goes back decades. It\u2019s difficult to read it all, almost impossible.<\/p>\n<p>\u201cAnd the \u2018Alien\u2019 world comprises, even before \u2018Prometheus,\u2019 four different movies, comic book series, novelizations, computer games. There are places online where people have assembled Wikis that attempt to reconcile every single instance of an Alien and explain how they all fit together.<\/p>\n<p>\u201cIt\u2019s come to a point where, as a matter of routine, the hard-core fans know the ins and outs of the canon better than any of the storytellers who are writing in those spaces, or the filmmakers who are making movies in those spaces. They actually become your first stop for research.<\/p>\n<p>\u201cWhen I needed to figure out some of the more obscure questions in the world of \u2018Alien,\u2019 I went to the fan bases online to look at how they were putting the big picture together. The big thrill for me, of course, was to participate in that world as a creator.\u201d<\/p>\n<p><strong>Q: Are there any of these worlds that you would like to inhabit?<\/strong><\/p>\n<p><strong>A:<\/strong> \u201cI\u2019ll skip the \u2018Prometheus\u2019 world, thank you very much. That\u2019s not the place I need to live. I like the bright, colonial, optimistic world of \u2018Passengers.\u2019 I would be excited to write more stories in that fictional universe.\u201d<\/p>\n<p><strong>Q: Can you talk about that? I guess you have to see how the first movie goes.<\/strong><\/p>\n<p><strong>A:<\/strong> \u201cI can promise you there will be talk about that.\u201d<\/p>\n<p><em>For a dissenting view on the scientific grounding for \u201cPassengers,\u201d check out this \u201cScience vs. Cinema\u201d video review by Andy Howell, an astrophysicist at the University of California at Santa Barbara.
