Marvel’s The Avengers (2012 movie): What did the Hulk mean when he said his secret was that he was always angry?

It seemed that early in the movie, he was not able to control himself when he turned into the Hulk. Yet, he seemed to be able to transform at will and also listen to orders or operate as part of a team in the later part of the movie.

If Banner had to just avoid getting angry in order to not be the Hulk, he’d never succeed, because of course it’s probably almost impossible for the vast majority of people to really just stop themselves from getting angry. But what do we do instead? We can’t avoid being angry, but we learn to control our TEMPER and we can control how we RESPOND to anger.

In the previous solo Hulk film, it ends with Banner learning that the key is less about the anger itself, than the literal physical reactions caused by the anger. If he can keep his heart rate down and his metabolism from responding to the anger and pain, then he can prevent changing into the Hulk. He maintains a constant state of anger at his situation, and at the state of the world, and at the people responsible for it, as a way to keep the emotional status constant and thus allow him to ignore controlling his emotions so he can instead focus his efforts merely on controlling his physiological responses to the anger.

With anger as a constant state, his body adapts, it returns to a moderated physical state most of the time, so anger itself won’t be a trigger. Only when he allows the anger to go unchecked and gives in to his body’s “desire”/urge to change, does he become the Hulk — unless he is too overwhelmed by physical stress to hold it back, like when he was severely injured early in the film on the Helicarrier. Otherwise, he can change into the Hulk at will because he’s already always angry, and need only let the change take place.
