I really do wish that the Hollywood mentality would go back to it's infancy and drop the whole bulls**t act they're doing now. Back then anyone could make a movie. There were no restrictions on who made a film nor about what type of story you wanted to tell. It was 'see-all' and 'tell-all' to your heart's content.
"All I need to make a comedy is a park, a policeman and a pretty girl." - Charlie Chaplin
Don't be fooled into thinking his movies were purely simplistic though. Chaplin got into trouble more than once for putting social criticism and commentary into his films. Such as in "The Immigrant" which pointedly touched on dehumanizing and inhumane treatment given to immigrants arriving in America.
Charlie Chaplin in "The Immigrant" (1917)The hottest water he ever got into though was with "The Great Dictator" in which he spoofed Hitler before America joined World War 2. At a time when many of the wealthy and elite in America sympathized with the Nazis and even more people advocated complete America-first isolationism. Chaplin played a double role as both the Hitler-dictator and an identical Jewish barber (the Tramp character in his only speaking role) who gets confused for the Hitler character at the end of the film. The final speech of "The Great Dictator" is not funny, but is in my estimation his greatest work.
Charlie Chaplin - The Great Dictator - final speechBecause of the calls for unity and the fact that the Nazis and the Italian fascists were notoriously brutal on communists and socialists* Chaplin was accused of being a Communist, though he always maintained he was merely a humanist. Reguardless FBI chief J. Edgar Hoover ever afterward suspected Chaplin of being communist and would years later block Chaplin's reeintry into America so that the actor would spend most of the rest of his days effectively in exile.
*Indeed this was one reason why Fascist regimes in Germany and Italy were initially well liked by the British and Americans, because they were seen as tramping down socialism. As Winston Churchill wrote approvingly of Fascist Italy in 1927 "If I had been an Italian, I am sure I should have been whole-heartedly with you from the start to finish in your triumphant struggle against the bestial appetites and passions of Leninism." Despite the Nazis putting "socialist" in their name as a sort of pacifying and popularizing but ultimately meaningless gesture.
And don't sugarcoat things too much. Life back then was crap too. If life was so grand at the turn of the last century, then why were humans so eager to advance and progress out of that life? And the World Wars weren't anything special from a human standpoint. From a technological standpoint, they were history-makers, but as far as sociological history is concerned, they were just another occurrence of humans mass killing humans. The only reason they were "world wars" was alliances were much larger thanks to advances in communications. Had Temujin begun his invasion 700 years later, he would have met stronger resistance on all fronts as well. A thousand years later, the Vikings may have never been able to expand beyond Scandinavia. Before advances in technology, the world was just as brutal and animalistic, but everything was restricted to the local level.
Oh it was never my intention to sugarcoat, as I said I would rather live today with modern medicine, communication, social advancement and plain creature comforts than any other time in history. However I must disagree with you that the World Wars were not significant, the first one saw bloodshed on a protracted and grand scale not really possible before the industrial revolution and the advent of the machine gun. (Said invention leading to unexpected ammunition shortages and casualty numbers for a few nations even though they'd been preparing for years.) The second one gave us the nuclear bomb and with it the ability to wipe out our entire species for the first time. They also left large parts of Europe and Asia effectively crippled for many many decades, leading the way for the rest of the 20th Century to be dominated by the United States economically and (consequently) culturally. I would say the effect these two major conflicts have had on our species are simply incalculable.
