Moulin Rouge Element Analysis

Note: I haven't seen Moulin Rouge, so my answers are just based off the opening scene.

Concept: Breif description of the story. It is set in the city of Paris in 1900. It is about a writer and the women he once loved. He will start to tell his story from the beginning.

Theme: A description of the movies overarching theme.
I think it's about love and lose. How easy it is to fall in love but how much it hurts when you lose it.
What do you see?
Everything started out black and white. Dark colours are seen in the first sweep of the city, then new, brighter colours are introduced. Filth and loud party's are contrasted.
What do you hear?
The man was singing, telling his story through song. The music starts off sad, the people at the pub are heard. The second shot through the city the party is the predominant sound. The music then starts to cheer up.

What do you feel?
Overall I feel sympathetic towards the man. In the begining there is a coldness to everything. Then later in the clip you feel glad that the city isn't as miserable as it first appeared. Happy that there are some people enjoying life.
What does it make you wonder?
I want to know the full story, what could of happened to make him so sad. Who is the Sparkling Dimond.
