I know that we have seen photos of them before but here are slightly more detailed pics of the costumes and look for Tim Burton's Alice In Wonderland. Above is Johnny Depp as the Mad Hatter. Below is Mia Wasikowska as Alice (with a white rabbit no less) and Helena Bonham Carter as the Red Queen.
As previously mentioned this is more of a sequel to the original tale - Alice, now 17 years old, as she escapes from a snooty party and follows a white rabbit down a hole, back to Wonderland. The White Rabbit is convinced that he has the right girl, the one who had visited the magical land ten years prior. But Alice doesn’t remember her past visit to Wonderland. The creatures of Wonderland are ready to revolt and are hoping/waiting for Alice to help them, but will she? Can she?
