Anyone who want's to see Goldberg machines designed by Goldberg and in action should seek out a 1930 Fox feature film that he wrote called "Soup to Nuts" . I came across it on a DVD Three Stooges collection (put out by force entertainment) as this was the film debut of Ted Healy and his Stooges (Moe, Shemp and Larry) four years before they started their long run of short subjects for Columbia (with Curly). The film stars Charles Winninger as the inventor and has Rube Goldberg in a cameo. The title card announces it as "Rube Goldberg's 'Soup to Nuts'" and it can be seen on the Wikipedia site for this film!.   Matthew BG Australia
