Alice in Wonderland sees a 19 year old Alice (Mia Wasikowska) returning to Wonderland, which is now under the rule of the Red Queen (Helena Bonham Carter). Though she has no memory of being in Wonderland before, she is quickly reunited with her old friends; the White Rabbit (Michael Sheen), the Caterpillar (Alan Rickman), the Mad Hatter (Johnny Depp) and Tweedle Dum and Tweedle Dee (Matt Lucas). It turns out that the residents of Wonderland have been searching for her; it is her destiny to take up the sword of the White Queen (Anne Hathaway) and slay the Red Queen's Jabberwocky (Christopher Lee), thus paving the way for rebellion against the Red Queen and the freedom of Wonderland.
The range of actors, both live action and in voice, was well chosen and brilliantly executed. Johnny Depp's Mad Hatter was (unsurprisingly) performed with a very unique twist. He seemed almost bipolar in nature; his usual upper class English light hearted nuttiness (with the inclusion of the lisp as a homage to the original animated movie) occasionally bled away to reveal a thick, gruff Scottish growl that spoke gibberish and had an air of violent insanity about it. It was a really nice contrast to the rest of the characters, who are plain old silly. There was a fantastic part where the March Hare (Paul Whitehouse) stops mid rant to exclaim "SPOON!" and thrust it in the audience's face, to which the entire cinema erupted in laughter. The casting of Alan Rickman, Stephen Fry and Christopher Lee as the Caterpillar, the Cheshire Cat and the Jabberwocky respectively was an excellent choice that would have only been further enhanced by the inclusion of John Hurt in there somewhere.
In conclusion, I'd recommend Alice in Wonderland to anyone, but make sure that it is seen in 3D in the cinema. It would make for a fun movie filled with quirky and well characters and a brilliant world that captures the strangeness of Wonderland as seen through Alice's eyes. Just don't expect much depth with regards to the storyline. Burton himself said that the original story was more like a series of events rather than a coherent plot, and while he tried to flesh out a story from this, the semi patchwork form can be seen. Still, a very fun movie to watch.
