The second trailer for the hotly-anticipated <em>Blade Runner 2049</em> film has landed, offering fans over two-and-a-half minutes of footage, much of it new. If you're hoping to learn much more about the story than you did from the first trailer which was released back in May, you may be disappointed. Here's what we gleaned about the latest installment from Denis Villeneuve (<em>Arrival, Incendies</em> and <em>Prisoners</em>) and Ridley Scott's (<em>Alien, The Martian</em> and <em>Prometheus</em>) return to the cult classic sci-fi. Some disaster seems to have befallen humanity – Los Angeles is surrounded by a giant array of something like solar panels or similar, presumably powering the city, while all areas outside the city seem to be mostly made up of smoke and dust. Philip K Dick's original short story which inspired the first movie, <em>Do Androids Dream of Electric Sheep?,</em> placed the action after something called World War Terminus, which wasn't mentioned in the first film. Has it happened by 2049? If you weren’t convinced Jared Leto’s freaky-eyed character was a baddie in the first trailer, you probably should be following his evil turn in the new trailer ("You don't know what pain is yet. You will learn", anyone?). The character is called Wallace, we learn, and he builds replicants (artificial humans created as a slave labour force). For what purpose, we don’t know, but he believes they are “the future” and bemoans his inability to build them fast enough. Maybe for cleaning up the earth, maybe for wiping out humanity. We don’t know. Ryan Gosling’s K, meanwhile, we already knew was a Blade Runner, or replicant hunter, searching for Harrison Ford’s Deckard, the elite Blade Runner from the original movie. He finds him. Though not without running into a spot of bother with Dave Bautista’s character, who appears to be a replicant with an attitude problem. Deckard, meanwhile, reveals that the reason he’s been so hard to find is because he has been “covering his tracks” for the 30 years since the original as he’s being “hunted.” By replicants? By something else? Again, it’s a mystery. Finally, Sylvia Hoeks’ still unnamed character, who already bore a striking resemblance in the first trailer to Sean Young’s super-replicant, and Deckard’s muse, Rachel from the first film. In the new trailer, she cries a solitary tear – an emotion sufficiently human to mark her above your average replicant, but not quite human enough to be human. Is she Rachel? Some other advanced replicant? Unfortunately, like so much else of the plot so far, we once again don’t know, but we only have to wait until October to find out, or perhaps be teased even further in order to set up a sequel? <em>Blade Runner 2049</em> is due to release in cinemas worldwide on October 4.
