Who is Charlie Chaplin from Flashback: A Brief History of Film and what is their importance?

Charles Spencer Chaplin (1889 to 1977) was an influential screenwriter, producer, and director. When he was 24, he was a popular performer mostly known for portraying an obnoxious drunk. This is a role he pulls from his real life, since his father died from drinking when he was only 52 years old. Charlie's mother was insane, so he and his half-brother Sydney spent much of their childhood living in London's streets. For a while, they lived in an orphanage. Chaplin always felt a sense of helplessness and deprivation, which influenced his filmmaking career.
