Why do humans speak English in Avatar?

It’s completely movie language, very normal, and very appropriate. That is to let the audience also experience the shock of the Navi people who have given up on themselves when they see Jake's return as the king.

Different from ordinary language, film language is an artistic language that directly appeals to the audience's audio-visual senses and conveys meaning through intuitive, concrete and distinctive images, and has a strong artistic appeal.

The screen image is the basic element of film language. The performances, scenes, lighting, colors, makeup, costumes, etc. that participate in the creation of the image image all play an important role in forming a special film vocabulary. The montage produced by the movement of the camera and the combination (editing) of different shots not only forms the composition rules of the screen image, but also perfects the unique grammatical and rhetorical rules of the film language.
