I can speak for most songwriters - those breakup love songs are so easy to write, as far as the inspiration and all that.
[ Blue is the Warmest Color ] was really a film about two people having to go through a relationship which everyone knew would lead to a breakup and the pain that that entails. Anybody can see that story, what leads to that, and identify with it. As a filmmaker, I wanted to construct this identification process with the characters so that you fully connect to their emotions and what their breakup [represents].
Love: a grave mental disease.
When one is in love, one always begins by deceiving one's self, and one always ends by deceiving others. That is what the world calls a romance.
