Okay, I've seen Faces of Death and I hate to tell you, but these scenes ARE REAL - that is why they look so real to you, unless we are speaking of different videos. The Faces of Death I saw was home shot footage of gruesome acts in different parts of the world... people being shot, hit by trains, etc. Seriously, I wish I never saw this video but an old friend popped it in the TV one day as a "surprise"
I have just been watching the SAW films and whilst they are not so scary, they are definitely the best psychologically scary films I have ever seen
In bollywood, there is a movie called "bhoot" that had scared me a lot, particularly the expression of the actress it was really scary
