When I rented this movie, I had no idae what to expect. Charlie Chaplin in a talkie?! I had just seen (heard?) how poor Buster Keaton's awful voice destroyed his presence as the classic stone-faced pantomine. Might Mr. Chaplin's performance in a speaking role be as sadly disappointing???
The answer in a resounding word was, "NO!" If anything, Chaplin's voice and accompanying ability to express himself with words enhanced his screen presence by providing a new dimension with which to appreciate his seemingly limitless talent.
I'm not sure just how to explain this other than the fact that I watched most of the film with a big grin glued to my face. I marvelled at the subtleties of Chaplin's performance which distinguish him not only as a silent movie actor, but as an actor of ANY era! In today's world of over-the-top silliness and questionable acting passing as good comedy, his performance is a clear indication that intelligent comedy is not an oxymoron and that the "King" of it is the same person as the king of slapstick.
If you're the kind of person who appreciates the subtlety in Woody Allen's humor, you will find yourself marvelling at "A King in New York" and you will see (and hear!) a part of Charlie Chaplin you may not ever have known existed.
