I'm not sure if anyone has noticed this yet, but here goes:

As you know there has been some questions as to why the four hobbit are being assaulted by the Nazgul (presumably at Weathertop), and Aragorn's absence during this assault. The questions are there because the hobbits were never assaulted by the Nazgul while by themselves in the book. Particularly at Weathertop, where the hobbits are believed to be at in the image, Aragorn is with them in the book, and fends off the Nazgul with a flaming brand of wood. But Aragorn is not in the image with the hobbits. Now quoting Tolkien's The Fellowship of the Ring, chapter 11, page 263, it says:

"Even as he swooned he caught, as through a swirling mist, a glimpse of Strider leaping out of the darkness with a flaming brand of wood in either hand."

Now look at the picture of Aragorn from the preview. Not only is he throwing a flaming brand of wood, but the background behind him appears to be Weathertop as well!
