Jake's Role In The Movie Avatar

I chose to watch the movie Avatar, because it always seemed like an interesting movie to me that I’ve only seen bits and pieces of, so it was nice to actually watch the whole thing.

When Jake’s brother is killed in a robbery, he decides to take his place in a mission on the distant world of Pandora (IMDb). He was able to do this because of the similar features and DNA, being that they are twins. Although Jake is a paraplegic due to a mission when he was serving as a marine, he was still able to complete the mission. I personally think he was great help to the project.
Another important role in the movie was Neytiri, which was played by Zoe Saldana. Neytiri is a navi (alien) that lives on Pandora.

After Jake and Neytiri met, she begins to fall in love with him, and eventually Jake joins the Na'vi to help Neytiri and the others save their tribe/village (IMDb). Neytiri is a strong and inspirational woman that isn’t afraid to stand up and take charge when needed.

She tries to seek wealthiness in Pandora from plant instead of mineral, which can be located at the bottom of the home tree. As you can see in the movie she likes plants more than human, which is why she is so good at what she
