In Hanna’s case, the film is structured around the toll that being a detective… takes on his marriage. In McCauley’s case, it’s the opposite. When we first see him, he lives in an empty, beautiful house, and is intimate with no one. Later, when he meets Eady and falls for her, he begins to open up. And suddenly, his emotional life starts to take a toll on his work. It’s this contrast that gives Heat such depth and turns it into something resembling poetry.
