Charles Chaplin in City Lights (1931)
The blind girl, now cured, after giving the rose to the Tramp, understands that he is the "rich man", the Charming Prince who haunted her dreams. The Tramp is anxious, and timidly asks her if she can see now. The answer of the girl and the breathtaking concluding smile of the Tramp create the most beautiful and inspiring ending ever. Because she had just realized that she saw the essential, which ironically, was invisible to the eyes.
