This film is unbelieveably great both stylistically and in its story of how "The Pepsi Generation" of the late-1960s put reckless impetuousness at a premium- which can lead to throwing away one's marriage one instant, and then changing your mind about it the next.
This is Richard Lester's greatest flick. "Hard Day's Night" was great, of course, but here you get a jump-cut style that includes both flashbacks and premonitions- it seems a very hip style and is suited to the subject matter of the film. And the shots are brilliantly composed- very dramatic visuals.
Also, you get about a minute and a half of the Dead playing "Viola Lee Blues", in their psychedelic heyday- complete multi-media experience.
And, in one scene Garcia and Weir appear amongst what are supposed to be the "neighbors", who are rubbernecking a denizen of their turf being carted off on a gurney. The neighborhood is Telegraph Hill, San Fran.- thought to myself: "why aren't these guys in the Haight-Ashbury?"- brcause they wanted to be in the movie!
Also, it has George C. Scott giving his usual great performance. And Julie Christie is believeably kooky.
Buy this one, man- one of the greatest all-time of celluloid creations. For real.
