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.

Inva Mula (born 27 June 1963) is an Albanian opera lyric soprano. She began her soprano career at a very early age. Her father (Avni Mula) and mother (Nina Mula) were also opera singers. She is also known for providing the voice of the diva Plavalaguna in the film The Fifth Element.

Even though she is a genetically engineered warrior, Leeloo was engineered by the Mondoshawan to fight an unimaginable, ancient Evil, not human wickedness. She is a strong yet vulnerable savior (Carpenter 1) who has never been exposed to human war.

The aria Diva Plavalaguna (acted by Maïwenn Le Besco; singing voice by Inva Mula-Tchako) sings in the film's most famous scene is “Il dolce suono” (“The Sweet Sound”), infamous as the ultimate example of the 'mad scene' that dominated the Italian bel canto opera period of the early 19th century.
