Matthew Solomon has gone to great lengths to explore the differences between Chaplin's 1925 silent release of THE GOLD RUSH and the changes he made for his sound release in 1942. For many years it has been a great mystery as to what Chaplin did when preparing the sound version. Did he just cut the titles and shorten the film as well as adding his voice for the narration and creating a wonderful music score? No. There was much more that took place. Today there are some Chaplin fans who prefer the original silent version over the later sound release -- BUT are they really seeing the 1925 release the way Chaplin originally released it? Solomon's research will give you a better understanding of the history of this classic film and what has happened to the film over the years. For any serious student of film this is an excellent read.
