The footage starts with the question, "Who are you?" and the answer, "I'm no one." It's not Arya Stark, but it sounds like it's Rey (Daisy Ridley), who is heavily featured, along with Finn (John Boyega), an angst-ridden Poe (Oscar Isaac), and Han Solo (Harrison Ford).Rey: "There were stories about what happened." Han: "It's true. All of it."
Yes, they made several movies. We also hear a voice (Kylo Ren?) say, "Nothing will stand in our way. I will finish what you started." What Darth Vader started?Solo's voice mentions "The Dark Side, the Jedi, they're real." The Force is all into us, we just have to let it in.
There's a ton of action, Finn appearing to take on Kylo Ren (Adam Driver) in the dark forest, and Princess Lea (Carrie Fisher) crying ... over whom/what? Is Luke (Mark Hamill) gone? He's nowhere to be found in the rest of the trailer.
