An absolutely delightful story here, with so many brilliant facets it's almost hard to know where to begin. To start with, it's always wonderful to see such a great comedian still being appreciated and enjoyed by so many people, so many years after he made his most famous films. It shows that the humour employed by the likes of Chaplin, Keaton, Lloyd and Laurel & Hardy can never date and, as the article mentions, this bodes well for the future in that there are new generations of fans who enjoy these films and so ensure that they will continue to entertain for many more years to come.
It is also a testament to the universal quality of early and, in particular, silent comedies in that they are watched and loved by people all over the world regardless of race, religion or politics. This, then, is one of the greatest things about silent comedies - they rely predominantly on the visual and so can be understood by anyone, anywhere. The early comedians like Chaplin also created "everyman" characters, that appeal to our human nature. We can relate to them, even after almost 90 years of social change, and in spite of differing cultures. What an achievement!
