Hands down. My favorite film of all time. I don't see it being knocked out anytime soon either. I have the tattoo, I think that says it all. But that's a story for another day. Right now we're talking opera.
Continuing a series of coincidences that have been happening lately, I first found out the song from the film was from a real opera when I played it for my Music teacher in class at Ramapo College freshman year. The scene in the film is actually two separate tracks, the first is the song "Lucia Di Lammermoor" ("Il dolce suono") and the second is "The Diva Dance" specifically created for The Fifth Element. My teacher recognized the first track right away and was intrigued by the second.
Of course the coincidence is found in my previous post. I saw Michael Ian Black perform in the same building I viewed the complete opera in years earlier and, in fact, the same building I attended Music class in. While checking for the correct spelling of the opera for my last post I landed on it's Wikipedia page. Turns out it's even more popular then I thought. A Russian pop singer named Vitas covered the film version of the song. I just had to get my hands on it. Thank you YouTube.
It doesn't happen often but I was speechless. A Diva, he is not. Oh well, the original will always be the best anyway.
