Interaction between Thomas + Christina
One of the subtle things in the action/direction of this film (and all the actors are at their best in EXOTICA), that I love, is the connection between Thomas & Christina when he questions her in the club.
Obviously Thomas initially doesn't want to be there, for various reasons. But the more he talks to Christina, the more intrigued he becomes. He has no desire for her sexually, but he seems to be fascinated by her and her story.
And mutually, Christina seems to relax and reveal secrets about herself to him, almost as if he's her psychiatrist... and perhaps she's needed to unburden these things for years. Although she & Francis share a special history, she can't discuss FRANCIS with Francis. And when we cut to the car, Francis is obviously shaken by rehearing/reliving the trauma about his daughter & wife, but on another level (upon rewatching) I think he's also saddened that Christina is revealing things to Thomas that she couldn't share with him personally.
Overall, all the character relationships in this film are intriguing-- but this is one that I always found unique. I also like the way that Thomas gradually gets pulled into the story. Even though he is initially coerced into the circumstances, he grows fascinated by the people he's dealing with.
The war is not meant to be won... it is meant to be continuous.
