For me:
The Avengers: where dr banner was walking towards the Chitaouri metal monster while with his head turned towards Captain America said: "that is my secret, i'm always angry"

Where Loki was telling Hulk off:
Enough! Enough! I am a God, you dull-headed creature and I will not be bullied ....{ next scene: loki being dusted on the ground like a rag doll, hulk looked @ him again and dusted him twice, called him "puny god" and walked on.

Also, where Captain America gave orders to the avengers, when he called out:
"Hulk?"
Lopsided evil hulk grin
"Smash".

You need to see these scenes...best scenes in the avengers.

In the apocalypse, Mel Gibson's; the scene where the black jaguar went after that dude but one of the bad guys went in front of it and got chewed out.

Fast Five: the last action scene on the bridge.
Real Steal: the last boxing match btw Hugh Jackman's robot and the Japanese robot.

I cant forget IP Man: where the guy faced the military man publicly using his hands to chop the guy on his chest, neck and sides of his stomach.

Maltilda: when she visited the evil teacher in her house and turned the time from 8:30pm to 9pm and then 10pm within 5 mins.

So many great movies.
Ratatouille: when Anton Ego was wowed after eating the food prepared by the rat and his later review and redemption.

Remember also, Shall We Dance? When thprivate investigator was telling Gere's wife about how we need witnesses to our lives otherwise we would all be living lives of quiet desperation.
Also, when he gave her the rose and the soundtrack Peter Gabriel's the book of love came on.
