Avatar, along with Titanic, became one of the most prominent works by James Cameron. In the film, people went to the planet Pandora, where the Na’vi (big blue creatures) lived. In order to make the expedition look the same, every human participant had an avatar — a body like a Na’vi that they could control.

Even though all of the blue-skinned characters looked like each other, there were still 2 visual differences between the true Na’vi and the people that arrived on the planet. Engineers created avatars with 5 fingers, while Na’vi only had 4. And also, true Na’vi didn’t have eyebrows. The stripes on the skin might look like eyebrows, but they are not hairs, while the avatars did have actual eyebrows.
