Answer: The Fifth Element
The Fifth Element was a 1997 blockbuster directed by Luc Besson based on a story he wrote as a teenager. The sci-fi film revolves around an adventure in the 23rd century, alien influences on Earth, and the importance of a young woman in protecting Earth from destruction.
That young woman, played by Milla Jovovich, is capable of speaking an alien language known as “The Divine Language”. While invented languages aren’t exactly uncommon in the world of sci-fi and fantasy movies, it’s rare for actors to actually become fluent in the language they speak on screen. Besson and Jovovich took the role the language played in the movie seriously, however, and would not only practice speaking in it, but would write letters back and forth to each other before and during the filming to practice with it. As the filming progressed, they became completely fluent and were able to have full conversations in the invented language.
We’re not fluent, but with the aid of a Divine dictionary, we can leave you a tourist-quality message to investigate: Awa cheba welso.
