A rare 1971 film by recently-deceased avant-garde architect Shusaku Arakawa (usually known only by his surname), this gets a large write-up in Amos Vogel's "Film As A Subversive Art". As described therein, it is basically a mock-documentary about a young child living as a homeless drunk in the Bowery. However, reading about films in Vogel's excellent book and actually seeing them can be two quite different experiences - the intense minimalism here coupled with the overblown music and the narration (written by longtime Arakawa collaborator Madeline Gins) makes this one of the most bizarre film experiences imaginable. Reading a little bit about Arakawa's subsequent work and ideas may offer some clues as to how to interpret it.
As I said, this is rare so please excuse poor picture quality (though maybe the pinkish tint here is deliberate?). I have to say that I found this film very heavy going, but Jonathan Leeds does a great performance as the child - wonder what happened to him? Make of this film what you will and, before anyone asks - I DON'T have "Why Not", Arakawa's other film.
