Here's the trailer for John Carter, the Disney version of Edgar Rice Burroughs' A Princess of Mars. The characters and sets look gorgeous. The story is by Andrew Stanton (who also wrote Toy Story, A Bug's Life, Monsters, Inc., Finding Nemo, Wall•E, and Toy Story 3).
I have high hopes for it, but I don't think the character of John Carter is that great, at least what I can suss out from this short trailer. He's too brutish, which isn't at all like Burrough's Southern gentleman. However, Stanton says he is a big fan of the novel and that the movie "feels like the book." We'll have to see!
