Diva (1981)

Directed by Jean-Jacques Beineix

Jules, a young Parisian postman, secretly records a concert performance given by the opera singer Cynthia Hawkins, whom he idolises. The following day, Jules runs into a woman who is being pursued by armed thugs. Before she is killed, the woman slips an audio cassette into his mail bag...

Was this the inspiration for the diva in Luc Besson's The Fifth Element (1997)? Apart from that, this made me feel uneasy on a number of axes.
