I don't think I can begin to put the way I feel about this film into words, so I'll use some quotes that I heard throughout the film instead.

"We never live the same day twice."

"I can't see what you see and you can't see what I see. How can I know what you see?"

"Can we only know the half truth?"

"You are his music."

"We live three times as long since man invented movies."
