Long before the Romantic Comedy genre developed the stifling limitations it labours under now, Charlie Chaplin directed this wonder.
No self-assured, handsome, and above all rich hero here. The plot is entirely driven by the heroine's assumption that The Little Tramp is a wealthy man and owner of an expensive automobile, and much of the film is taken up by TLT's attempts to live up (or down) to this assumption. Trying to earn, beg or borrow the money to clear the heroine's back rent and buy her an operation to recover her sight brings him into many comic situations (including the hilarious and brilliantly choreographed boxing scene).
But TLT's love is an unselfish one, for the operation he intends to buy her will also expose the truth about himself and bring almost certain rejection and humiliation. Elsewhere in the film, wealth and the wealthy are given short shrift. Check out the alcoholic millionaire who is friendless and can only relate when he is drunk. How Chaplin resolves TLT's dichotomy in the final scene is as elegant as it is moving and satisfying.
This film is B&W and silent (something Chaplin insisted upon, even though he could have made a talkie) and is a perfect example of how narrative can be driven without dialogue.
City Lights won't change your life. But as a depiction of how love can transcend social and physical barriers, and how money can both create and destroy, it is unequalled.
