Press Release for the second Alice in Wonderland trailer:

Coming to the big screen in Disney Digital 3D™ on March 5, 2010, ALICE IN WONDERLAND is an epic 3D fantasy adventure starring JOHNNY DEPP as the Mad Hatter and MIA WASIKOWSKA as 19-year-old Alice, who returns to the whimsical world she first encountered as a young girl, reuniting with her childhood friends:  the White Rabbit, Tweedledee and Tweedledum, the Dormouse, the Caterpillar, the Cheshire Cat, and of course, the Mad Hatter. 

Obviously by the description this is not the same old Alice in Wonderland that was expected. Alice has returned and apparently by the end seems to be a warrior or “champion” as the White Queen (portrayed by Anne Hathaway) refers to her. I personally am a FREAK for all things Alice so this new imagining looks amazing!
