Cinematically, Titanic uses scale to argue its point. The camera soars and then narrows; orchestral swells crash against silences that let the actors’ faces hold their notes. The score—big, aching, sometimes indulgent—functions like wind through rigging: it can propel you, suffocate you, or empty the air until only the essentials remain. In the film’s quietest moments, when two people sit in relative darkness and say things that might be ordinary in another life, the music steps back and the truth steps forward.
