This clip, shared by The Criterion Collection, shows Charlie Chaplin at work on City Lights. He was a perfectionist and didn’t settle until he was satisfied. The audio commentary is a window into the process he followed. Despite City Lights being Chaplin’s fifth feature film, and after countless short films, the production lasted almost two years. Shot without sound, although sound films were becoming more and more mainstream, City Lights is also the first film where Chaplin took on writing the score, on top of co-writing the screenplay, directing and acting in it.
