Revolver

[AliFlump]

Hi All, i saw Revolver last night and i thought it was good it kept my attention but what was the thing they were going on about that 'it makes you believe that it is you when it isnt'? my boyf reckons it is greed and some people can overcome it and other cant? anyone else seen it and have any theories?  i know this has been asked before but thought somemore people might have seen it since then. Thanks
