Charlie Chaplin was one of the most versatile and flexible of all comedians and actors during the beginning of the 20th Century. He was unafraid and experimental in his approach. He even experimented with dark humor – a most unusual trend that was imitated by others. Improvisation characterized his silent work, and that tended to be a challenge to his fellow actors. Chaplin was, however, very well-liked among his colleagues as well as respected by them.
