Top of the charts
Now, we know what you are thinking, that of course, Star Wars was on the top of the box office charts when it came out. But we are not talking about ticket sales at the movie theatres, we are talking about musical charts. Star Wars took over that domain as well.
When it was released in the late 1970s, the theme to Star Wars was made into a disco version and topped the musical charts for a few weeks. It was sort of a disco remix with multiple Star Wars songs thrown in. Two weeks at the top of the music charts is not bad for a feature film.
