USC professor creates an entire alien language for 'Avatar' – Frommer has spent four years laboring on the language of the Na'vi tribe and his work will not end on the day of the film's release. He plans to keep expanding the language until he's, well, blue in the face. "I'm still working and I hope that the language will have a life of its own," the professor said. "For one thing, I'm hoping there will be prequels and sequels to the film, which means more language will be needed. I spent three weeks in May, too, working on the video game for Ubisoft, which is the name of a French company. That's not a French word, though, I don't know where they got Ubisoft."
