1. The film is titled "That Obscure Object of Desire," due to the fact that it deals with something that is can be frustrating, and is the least talked about aspect of a relationship - sex. However, not just sex. Matthieu and Conchita parallel the characters of Calisto and Melibea, being sexually attracted to one another. As with most men, Matthieu is filled with desire at the prospect of sleeping Conchita. However, like all men, desire is instantly lost upon climax. To be frank, it's like losing your virginity - it only happens one and it's never the same. This is the basis of the thought the parades through Matthieu's head, and causes him to lose his sexual deviance in relation to Conchita.
2. Terrorism is used as a background to the film, due to the fact that terrorism does indeed parallel sexual attraction, sexual intercourse, and orgasm all at once. Sexual attraction is the build-up between two opposing forces in whatever context before the strike. Meanwhile, sexual intercourse is the movement which leads up to the point at which an act of terrorism is carried out. Finally, orgasm is the happening of the event, and thus, its lasting results, which parallel orgasm in the fact that whatever motive a person had going into it is gone, and their head, devoid of any sort of longing, desire, and arousal. Once clarity refills a person's head after intercourse, they are able to really think and concentrate on how they feel about their partner, or what they just did, much like the effects of a terrorist attack are felt and thought about by everyone, primarily the involved party, being the government.
