Sony Pictures Imageworks designed the visual effects sequences. Burton felt 3D was appropriate to the story's environment. Burton and Zanuck chose to film with conventional cameras, and convert the footage into 3-D during post-production; Zanuck explained 3-D cameras were too expensive and "clumsy" to use, and they felt that there was no difference between converted footage and those shot in the format. James Cameron, who released his 3-D film Avatar on December 10, 2009, criticized the choice, stating, "It doesn't make any sense to shoot in 2-D and convert to 3-D."
Alice, an unpretentious and individual 19-year-old, is betrothed to a dunce of an English nobleman. At her engagement party, she escapes the crowd to consider whether to go through with the marriage and falls down a hole in the garden after spotting an unusual rabbit. Arriving in a strange and surreal place called "Underland," she finds herself in a world that resembles the nightmares she had as a child, filled with talking animals, villainous queens and knights, and frumious bandersnatches. Alice realizes that she is there for a reason--to conquer the horrific Jabberwocky and restore the rightful queen to her throne. Written by Jim Beaver <[email protected]>
In 1932, Walt began toying with the idea of making an animated feature film and repeatedly turned to the idea of making a feature-length animated/live-action version of Alice starring Mary Pickford, and even purchased the rights to Sir John Tenniel's illustrations (still under copyright at the time). However, these plans were eventually scrapped in favor of Snow White and the Seven Dwarfs , mainly because Disney was put off by Paramount's 1933 live-action adaptation. However, Disney did not completely abandon the idea of adapting Alice , and in 1936 made the Mickey Mouse cartoon Thru the Mirror .
