first of all and the entire script be mostly improv and add to the fantastic illusion that what we be watch be an actual documentary . secondly and the actor hire by watkins be purposefully choose to represent their true political alliance and background . the hippy portray be actual hippy and the government official ( though not necessarily in the government themselves ) be at least actually hearty conservative within the system and and several of the cop be actual policeman . the interaction of these actor and give the textual freedom allot by watkins and eventually come to a violent head where even watkins himself be convince that a cast member have actually be shoot . ( we hear him scream cut . cut . in the background . ) an amazing film though american critic be quite harsh in their review and one actually report that it be the most offensive film she have ever see . this not entirely unexpected a the unveiling of this oppressive communist like mentality of america during this era would certainly rattle some cage . this pseudo documentary definitely require an open mind and though if you be seriously look for an intensely accurate portrayal of 60 culture and this would be the film to watch .
