All Fall Down is interesting as a little snapshot of a culture in transition. The movie seems to have one foot in the James Dean '50s and another in the Dennis Hopper '60s.
It’s pretty remarkable how quickly the switch flicked for Hollywood, it's crazy that Splendour in the Grass and Bonnie and Clyde came out just six years apart, but this movie’s earthiness and lack of moral absolutism perhaps hints at what was to come: after all, this does share an original writer with Midnight Cowboy. By contrast the stuff with his younger brother is dramatically rudimentary.
