I enjoyed "Blast of Silence" very much. However, watching this making of film after made for a very satisfying viewing experience. This is because learning about the very, very, very low budget and compromises made to make the film really made me appreciate Allen Baron even more. For example, while he wrote and directed the film, the only reason he starred in it was that Peter Falk (a friend) couldn't do it for next to no salary--and they couldn't afford anyone else! For the most part, Baron just walks around the filming locales in New York City and talks about how he made the film, how it was marketed and how it was recently re-discovered. All in all, a very intriguing film--one that new filmmakers SHOULD see as it will help them to understand that excellent filmmaking doesn't need huge budgets, explosions or even big-name actors.
This featurette, by the way, is included with the film in the Criterion release.
