"Unknown Chaplin" is an interesting program--from two authorities on film history and preservation, Kevin Brownlow and the late David Gill, two men I'm thankful to for many of the restored movies I've seen. I consider Charlie Chaplin one of the greatest filmmakers ever, in addition to being the funniest man I've ever seen. This three-part television series shows cut footage from Chaplin's films, providing a unique look at the filmmaker's perfectionism and improvisational approach.
The first two episodes are especially telling. "My Happiest Years" features cut footage from his Mutual shorts "The Immigrant" and "The Cure", where Chaplin repeatedly retook scenes, improvising the comedy and narrative in front of the camera. And, "The Great Director" includes a nice look at the struggle between Chaplin's perfectionism and his unprofessional leading actress during filming of "City Lights". The last episode, "Hidden Treasures", shows a comedian who continued to work when not filming movies for release and how some of the gags in his films evolved over time. There's also a sequence from his aborted film "The Professor" and cut scenes from more of his films. Overall, "Unknown Chaplin" is worth watching for everyone seriously interested in Chaplin's art.
