Quote from : The Bridge on the River Kwai Movie

Colonel Saito: I am Colonel Saito. In the name of His Imperial Majesty, I welcome you. I am the commanding officer of this camp, which is Camp 16 along the great railroad which will soon connect Bangkok with Rangoon. You British prisoners have been chosen to build a bridge across the River Kwai. It will be pleasant work, requiring skill, and officers will work as well as men. The Japanese Army cannot have idle mouths to feed. If you work hard, you will be treated well, but if you do not work hard, you will be punished!
