Is this sort of an autobiography?
I couldn't help but notice that many of the elements in this film reminded me of what I have read and heard about Chaplin's own life. If so I probably missed a lot of things but here are some of the things I noticed were reminiscent of his own life (spoilers obviously):
The older man having a younger woman/girl as "wife".
Mentions of his act being a tramp character.
The comedian having been famous and celebrated when he was younger only to have his career fade as he aged. Being banished from the stage could be a reference to Chaplin being kicked out of the USA.
He speaks of finding a quiet place in the countryside - something Chaplin did in Switzerland just a year after the release of this movie.
