Na'vi - The Language Of Avatar
Linguistics expert Professor Paul Frommer, from the University of Southern California, is the man behind the fully functioning alien language in the hit film, Avatar.
He replied to an email from James Cameron looking for a linguist to come up with an alien language and the pair worked together for four years to develop the Na'vi language used in the film.
Professor Frommer spent many hours on the set, helping the cast members fine tune their alien language speaking abilities.
Professor Frommer's hope that Na'vi will one day match Klingon as the "gold standard" alien language may become a reality, as there is now a Learn Na'vi website!
