Disney very recently released another trailer for Alice in Wonderland that will play before Avatar this weekend. It's packed with a ton of new footage and enough revelation of the plot for us to know this won't just be a remake with a twist of Tim Burton (ala Charlie and the Chocolate Factory) but will have its own unique story that takes place after Alice has already come and gone from Wonderland. I suppose its a bit of a sequel but it looks more like Tim Burton's expensive version of fan fiction.
All of the characters look wonderful, especially Helena Bonham Carter with her big head on a little body. Johnny Depp gets a lot of screen time in the trailer and Anne Hathaway gets very little so lets hope that trend continues in the film.
