The segment where Clooney was being tortured ( fingernails pulled off) and saved just prior to having his head SAWED (not sliced) off by the religious leader was frightening.
I had heard about this scene prior to viewing and had the fast forward button ready. Chinese torture techniques indeed.
You noticed, didn't you, that it was the Hizbollah bigshot who called off the dog, right?
In RL, the Hizbollah gunsels would have been running out for cigarettes and hot coffee and handing the guy instruments as the torturer whistled while he worked.
