A suggestion: "Most culturally prominent" works better than "most influential" The only thing Wikipedia is going to tell you is how many other Wikipedia authors cite something. A movie can have terrific influence globally but in an indirect manner, influencing a generation of writers and directors, for instance. Likewise it could have influenced a lot of people, just not people who have anything to do with Wikipedia. Wikipedia is more like a popularity contest. "Birth of a Nation", for instance, had a huge impact all across North America -- but nobody is around anymore to cite it, so it's mostly lost to time.

I see you've changed the title. Cool.

Nice work!
