Consider (2003). The line “For Frodo” is rousing, but the true dramatic peak comes earlier: The charge of the Rohirrim. Before the spears lower, we have spent hours watching hope die. We saw Théoden possessed by Wormtongue, his son Theodred buried, and the fortress of Helm’s Deep nearly fall. When he finally shouts, "Death!" and rides into the Pelennor Fields, it isn't just battle; it is the culmination of a king reclaiming his soul. The drama works because we know the weight on his shoulders.
The final act of Moonlight features a reunion between Black (Trevante Rhodes) and Kevin (André Holland) that is thick with unspoken history. As they sit in a quiet diner, the drama isn't found in what they say, but in the tension of what they can't say.
Before discussing specific films, we must define the mechanism: . The most powerful dramatic scenes occur when a character can no longer lie to themselves or others.

Christopher Nolan’s The Dark Knight is a blockbuster dressed as a tragedy, and its centerpiece is not a car chase, but a conversation in a stark white room. The scene: Batman interrogates The Joker.
