If you were interested in the Hollywood version try the original TV documentary!
Jon Ronson produced and narrated a three part documentary for the BBC Channel 4 titled Crazy Rulers of the World. The three parts were titled "
The Men Who Stare at Goats",
"Funny Torture" and
"Psychic Footsoldiers" respectively. All three parts were interesting and worth watching.
The easiest way to watch all three parts is downloading the torrent from
somewhere.
