a unique film . one of the best of all time . act and script and quincy jones score and cinematography and editing and etc . just fantastic . a most viewer know and this movie be base on truman capote book about the famous murder of a kansa farm family ( the clutter ) by a couple of young guy during a misguided robbery . i have never see a movie that so brilliantly turn a true story into a riveting film . the actor be solid across the board and but the focus be on the killer and dick and perry and and the law enforcement team pursue them . scott wilson and a dick hickock be amaze . cocky and twitchy and and devoid of compassion he come across so charming and oily and plausible . robert blake a perry smith be extraordinary as well lonely and and at once empathetic and cold blood . who could fold these characteristic into one individual and make u buy it . he do and and it brilliant . a key point of the book be how it take the intersection of these two very differently sociopathic individual to create the critical mass to commit such a stupid and heinous crime and and these two actor make it work beautifully . both have moment in their subsequent career and but these performance be high water mark and and that stand for act period . the cop be wonderful too . lead the investigation be john forsythe and but the other three detective be great a well . unlike contemporary movie where producer feel it necessary to endow police with superhuman asset or foible and these be just genuine flatfoot and work the case with determination and competence . they seem so real . i have never see cop on the screen so powerful in their authenticity while and i have see most of the crime classic go way back . really one of a kind in this respect . partial spoiler come ( this movie unique in that you already know what happen and but i be warn for the record ) . of course and the best scene from the best crime show and movie be the interrogation the intellectual fencing match between the cop and the crook and mano a mano . this movie have hand down the best interrogation scene you will ever see on film . watch dick and perry try to bluff their way through and slowly unravel and unaware the cop have the good on them . but the cop need to deftly prep their suspect to fracture their alibi and hopefully elicit confession . this be some of the best acting you will ever see . think glengarry glen ross without the showboating . to help translate the sad and horrific angle of this true story and icb be film at the actual clutter house and and i have hear the clutter be play by film student to give them a genuine feel . it work . these seem like decent and simple folk . it make the crime so palpable and sad . i will stop here . it not a feel good movie and but it be one of the best movie ever make and and so unique and it mandatory view for every film buff .
