The "Divine Language" spoken by Leeloo is a fictional language of 400 words, invented by Besson. To practice, Jovovich and Besson held conversations and exchanged letters in the language.

In film. Mula is perhaps best known to Western filmgoers as the singing voice of the Diva Plavalaguna, played on-screen by Maïwenn Le Besco, in the 1997 film The Fifth Element, where she is credited using her then married name as Inva Mula Çako.

According to the dictionary of the "divine language" that director Luc Besson put out, Leeloo's full name "Leeloominaï Lekatariba-Lamina-Tchaï, Ekbat de Sebat" loosely translates as "Precious Stone of the Earth, Defender of Light and Life, the Honorable".

The greatest strength of The Fifth Element is by far its sense of humor, which is something that most big-budget science fiction films never even attempt, much less manage to pull off.
