Charlie Chaplin stuck to his theories for a long time. In the talkies era, he made two silent movies- City Lights (1931) and Modern Times (1936); although the latter had some talkies part, including a song and dance scene by the genius himself, it can safely be clubbed under the silent movies.
Chaplin made 5 talkie movies in his lifetime, out of which in 4 of them- The Great Dictator(1940), Monsieur Verdoux(1947), Limelight(1952) and A King In New York(1957)- he was the protagonist and one- his last movie and the only colour movie of his lifetime-A Countess from Hong Kong(1967), he directed and played a small cameo.
