Science fiction has long been an arena for creative minds to wonder what the future holds -- and more specifically, if we, as humans, are the only living beings floating around this vast tapestry we call the universe. As we enter an age where vacations to Mars could soon be a reality, many of the questions sci-fi poses might soon be answered: Is there other life out there? If so, will our galactic neighbors be peaceful? How will we communicate with them, and what, if anything, can we gain from one another?
We likely have some time to keep speculating. And Arrival, which hits theaters this weekend, does so in graceful fashion, showcasing a mysterious race of aliens with mysterious priorities. To get you in the mood for Denis Villeneuve's awe-inspiring language-breaching, mind-bender -- as well as the near future -- we've catalogued a variety of our favorite alien movies below, all of which you can stream right now.
