This is an utterly brilliant, utterly unforgettable film, by some distance my preferred movie of all time and likely to remain so. No other film ive seen has the capacity to probe so deep into the human conscious with its stark imagery, climactic storyline and maddening atmosphere. Duvalls performance is possibly the best ive seen in a supporting role from any actor, perfectly grasping the arrogance of the perceived american presence in Vietnam, whilst also delivering several laugh out loud classic lines flawlessly.The military attack on the Vietnamese village is as exhilarating an experince as you will find in any motion picture, but from here on the film submerges itself in darkness as we travel up river, all the time the myth of colonel kurtz looming over the piece with a heightened sense of impending doom and anticipation.The whole film builds to the meeting of Kurtz, and as we finally approach the truly haunting closing setting we are as intrigued to meet him as Sheen. Whilst Brando is undoubtedly ott, it is a credit to his sheer aura that he is able to live up to this mythical character without us being dissappointed. Cinematically this film is a dream, every shot would make a fine still photo, and the ending will have you gripped to your seat. The images in this film will haunt your mind for days on end i assure you. It is ,of course, the best war movie ever made, but it is far more than that, it is a study in human nature and enthralling psychological viewing. If you dont like this film, you have to ask yourself, do you really like movies at all?
