Alice in Wonderland (2010) is a fantasy movie directed by Tim Burton, starring Johnny Depp and Helena Bonham Carter and released by Walt Disney Pictures. The film was inspired by fantasy novel Alice's Adventures in Wonderland written by Lewis Carroll. Although it receiveda mixed reviews from critics and various websites, it was also nominated and won many awards, e.g. for visual effects or costume design.
Alice in Wonderland movie is a mixture of live action and computer animation, with heavy use of VFX and green screen. Above behind the scene footage shows how some of the scenes in the movie were shot and how many objects had to actually be added in post production stage by VFX crew. Moreover the Red Queen (played by Helena Bonham Carter) had to be 'created' digitally due to unnatural proportions - massive, funny head and quite small body. Another interesting fact is that the movie were originally shot in 2D (with one camera) and then converted into 3D.
As it action is set in fantasy world, the amount of CGI used shouldn't really be suprising. Still, even with that, Burton managed to keep it fairly realistic and believable. The interactions between human and animated characters seem natural thanks to great amount of CGI usead. Wired published an interesting article about visual challenges set by Alice in Wonderland.
