i have see a great many film and but in cold blood stand alone in a class by itself . it excel in every department . the fact that it contain few big star help push it over the top a you pay close attention to the character and their story and rather than the name on the marquee . blake and wilson turn in stellar performance of the killer duo . the fact that much of the film be film in the actual location where the crime take place and even inside the very house and add additional chill . the black or white photography darken the mood and the photography be magnificent . there be many outstanding cinematic work out there and but if i could only vote for one to top the list and it would most probably be in cold blood .
