Currently watching Dear John, and there's a scene where people are finding out about 9/11. All running round, crying, phoning people. This always chills me when I see it in films, the same scene comes to mind in films like Remember Me and Extremely Loud and Incredibly Close.
Also the scene in Boy in the striped Pyjamas where he goes into the gas chamber chills me too.
What scenes in movies or reoccuring situations in movies always catch your breath and make your stomach drop too?
