Avatar is a 2009 American epic science fiction action film
written and directed by James Cameron.
Themes and inspirations
For the film's floating "Hallelujah Mountains",
the designers drew inspiration from "many different types of mountains,
but mainly the karst limestone formations in China.
The look of the Na'vi – the humanoids indigenous to Pandora
– was inspired by a dream that Cameron's mother had, long before he started
work on Avatar. In her dream, she saw a blue-skinned woman 12 feet
(4 m) tall, which he thought was "kind of a cool image". Also he
said, "I just like blue. It's a good color … plus, there's a
connection to the Hindu deities, which I like conceptually." He
included similar creatures in his first screenplay (written in 1976 or 1977),
which featured a planet with a native population of "gorgeous" tall
blue aliens. The Na'vi were based on them.
Visual effects
A number of innovative visual effects techniques were used
in the production of Avatar. The director planned to make use of photorealistic
computer-generated characters, created using new motion-capture animation
technologies he had been developing in the 14 months.
Innovations include a new system for lighting massive areas
like Pandora's jungle,[97] a motion-capture stage or "volume" six
times larger than any previously used, and an improved method of capturing
facial expressions, enabling full performance capture. To achieve the face
capturing, actors wore individually made skull caps fitted with a tiny camera
positioned in front of the actors' faces; the information collected about their
facial expressions and eyes is then transmitted to computers.
