The Rubber Gun

I saw this movie in my film school days and still remember it as one of the best films I saw that decade (70s)....and I saw many many very good films. I have hoped to see it again, but it never reappeared, not even on video. It has an interesting sorta dual plot line and very good realistic acting and dialog. Actually - the most realistic dialog of any film I have ever seen. I think I read that most of the actors were non-actors and much of the acting was improvised, which makes their performance even more amazing. This is one of several films I saw I my film school days that I saw once, when it made its rep house circuit, and then disappeared forever....that I wish would be resurrected on video or DVD.
