Avatar Movie and Star Wars Movie--Following Inspiration

A few days ago a ninth-grade student in English class was watching the Star Wars movie for the first time.  The Avatar movie was just released last Friday.  James Cameron, director of the Avatar movie, said that the Star Wars movie, written and directed by George Lucas,  movie was an inspiration for the development of Avatar.

Were I a full-time English teacher this year, I would probably assign an extra-credit project to view both Star Wars and Avatar and to track evidence of Star Wars inspiration in the Avatar movie.
