Chalice. Oh my gosh!! It totally drew me into opera too but guess what??? It was all natural! The same woman who was Plava Laguna sung that song again in an opera concert and I watched it on Youtube! She was unbelievable and got every pitch that the movie showed! Evgenia Laguna is the woman's name so they based Plava after her.

The opera scene in the Fifth Element wasn't the whole thing either.
