I saw this short film in1973. It was a comedic Look at Los Angeles life during Vietnam. I can't remember the details but my overall reaction was that it was "roll on the floor funny." It did reflect 1971 quite well. I would buy a copy if it were available on DVD.
It did not win an Oscar that year. I did not see all the competition for that year but this one sticks in my mind as worthy of one.
Ken Greenwald is a very talented young man. I also recall him as an actor in a car rotary engine commercial. Regretfully,, he did not produce another film until about 2006.
