<human>:  Where does the title of the movie ‘Sunset Boulevard’ come from?
<bot>: The title Sunset Boulevard comes from a line in the movie. The line is “I am big. It’s the pictures that got small.” The line is spoken by a character named Joe Gillis, who is a screenwriter. The line is a reference to the fact that the movie industry has become more focused on making small-budget movies, rather than big-budget movies.
