What theme of a show, song, movie, or story can be compared to the theme of shakespeare's sonnet #32?

The theme of the movie Moulin Rouge. The main character Satine is a courtesan but dies as an actress in the arms of her lover Christian. She tells him to write about their love, about their story, and indicates to Christian he should not be sad but rejoice in the glory of the story. Shakespeare's mention of poems can be compared to the love story that are both being told to be remembered, for the great amount of love and effort put into them, and should not be compared to any other.
