Watch the whole trailer!
UPDATE! This extended trailer explains what's going on in typical Abrams' fashion.
By explaining nothing at all.
It's a book! Or at least, part of it is a book. Oddly, it's being handle much the way a movie or television show might, with Abrams creating the idea and then delegating the actual script to a writer, in this case Doug Dorst.
Dorst is the creator of two previous works, the novel Alive In Necropolis and the short story collection The Surf Guru, both of which are critically lauded.
This may be reading too much into it, but the book looks like a prequel to another work, as the trailer states this is only the beginning and everything he wrote is true. So if the novel is the "truth" then the mystery is just beginning. Or maybe it's just a book.
