April 1972, Charlie Chaplin returned to America for the first time in 20 years. It was an historical moment remembered by all who saw it. It was the first time I was introduced to Chaplin, and I have been a fan of his, ever since.
Here is a short video version of the actual moment. (Hopefully, someday, The Academy will share the full moment, without any cuts.)
