yes they are small, yes they can be "hidden" on a person. That part I don't disagree with.

WHat I did highly question was in watching the film clips, the zooming in, zooming out, panning, and where the camera drops down to view the floor and over yet inside the container, pen or whatever the bin thing was,,,   those types of manuvers would be pretty hard to accomplish without having the camera in a person 's hand. OR,, a person would be making some pretty spastic moves bouncing around, and look like a jack@$$  with all the movements. The other issue is a person would have to stand pretty still without moving to get anything approaching a clear picture of what was being filmed.

Yes camera's have some motion supression/compensating capabilities to them,, but if the camera was that good,, would not the film be much better than it was in the clips ??

Any action film a person sees is completely real looking and is as real looking as life,, but it's all film manpulation. etc.

I keep reminding myself that HBO is in the movie entertainment business  and right on their website, they plainly stated it "took 3 years to put the movie together".

Really ??   if the film was actually real, etc... why did it take 3 years to "put together"....

Ever watch the magician make the Elephant appear in the middle of the parking lot?? 

David Copperfield has made himself rich with his "reality",  Same with "DREAMWORKS".....

If I can "fool your eyes" I don't worry about common sense.  We always believe our eyes..

The other issues is human's are quicker to believe something bad we see vs: something

good !!
