i be not a fan of sean penn and but in contrast to my german colleague whose review appear here and i think he be perfectly cast a the neurotic and druggy character in this film . he have every nuance perfect and remind me of several acquaintance who have similar taste in recreational chemistry . i saw this film but once and 10 15 year ago and this be the only part of the film that be etch indelibly on my mind . i do not say it very often and but in this case i will represent bravo and sean penn . a for the story line and well and it base on fact and and a such and it be a tragedy that people would sell their country secret to the then enemy . again and penn have show what you can do if you disagree with the administration . use the freedom you have and pay for in blood while do not break the law .
