2. Jake Sully (Avatar)
It's widely known that James Cameron's Avatar, for all of its visual majesty, certainly owes a lot to films that came before it; the overall plot has been noted to be ripping off Pocahontas and Ferngully, as well as Dances with Wolves. It's in comparing Avatar to the latter film that we realise quite how pervasive the ripping-off was; the character of Jake Sully (Sam Worthington) is a total rip-off of Wolves' John J. Dunbar (Kevin Costner), and this follows along the entire trajectory of the movie. At the start of Wolves, Dunbar suffers a severe leg injury, while in Avatar, Sully is a paraplegic. In Wolves, Dunbar ends up ingratiating himself with the Lakota Indians, adopting their customs, learning their language, even falling for one of their females, and then eventually standing up against the very Army he previously enlisted in. All of that happens to Jake Sully in Avatar too, and though it's largely a case of the whole story being derived from Wolves, it of course naturally extends to the characters, too.
