I'll just mention one movie for now.
"The Bridge on the River Kwai"
When the British POWs are walking to the prison camp for the first time, they're whistliing the Colonel Bogey March, which always sends chills over me.
Then when they're ordered to build the bridge, and Alec Guinness defies orders, the Japanese commander has them punished by standing in the sun all day, then finally puts Alec Guinness in the hole, where he tries to break him.
The commander then realizes he can't break him, and he himself breaks down in tears when he realizes that if he can't get the bridge built on time, he'll lose face in his country's eyes.
When Alec Guinness walks out of the hole in triumph and walks stiffly to the prisoner's quarters, now that's a great scene.
The ending....the ending is madness.
