... while he himself was basically exiled in a strange land. 1957's "A King in New York" shows Chaplin at the end of his film career. In fact, it is the last film in which Chaplin himself stars. Refused permission to reenter the U.S. in 1952 due to the idea that he held anti-American beliefs, he actually made this film about a deposed European king in New York in England. The film suffers from production values that are not as high as they were in Chaplin's earlier films, and if you have the version Warner Brothers put out in 2004, the commentary points out that Chaplin had much trouble making this film mainly because he was not dealing with familiar personnel in his own studio as he had in his earlier efforts. The film's political statements are heavy-handed, but there are still some good comic turns by Chaplin and his viewpoints and comic bits on America and rampant commercialism and consumerism still hold up today. In fact, they are probably much more relevant today than they were when this movie was first made.
If you are curious about Chaplin's work you need to eventually view this film, just don't start your journey here. If you are just starting out, I recommend you view Chaplin's Mutual Comedies. These are 12 two-reel comedies Chaplin made in 1916 and 1917 and show his comic technique evolve from the pants-kicking fests of his Essanay and Keystone films into the sophisticated technique he had from the end of the series onward. Also, the Mutual period was named by Chaplin himself as the era in both his personal and professional life in which he was the happiest.
