Leeloo’s Divine Language is Real
The first part of the film opens with Leeloo speaking in a language that sounds like gibberish. She wasn’t merely reciting common phrases, though; director Luc Besson created a whole extraterrestrial tongue from nothing, dubbed The Divine Language.
He gave Milla Jovovich access to a lexicon containing roughly 400 real terms, but much of the mystery surrounding her persona stems from the fact that it’s unclear exactly what she’s saying. That’s the reason why when she speaks, there are no subtitles from Divine Language to English.
