Here’s the first official trailer for Disney’s upcoming film, ‘John Carter.’ It’s an odd way to retitle Edgar Rice Burroughs’ science fiction novel, ‘A Princess of Mars.’ But that’s what they’ve done. I don’t imagine there are too many people who will go see a movie named for someone called John Carter. But anything is possible. If you’d like to put up with some very bad writing by Mr. Burroughs, you can listen to Candlelight’s complete audio book version of the novel. I’m not sure why I recorded it at all. Burroughs turned what should have been a short story into a novel by making all of his sentences run the length of football fields.
