A study released in November 2018 lists the most influential films of all-time, as reported by the University of Turin. Interesting. It sounds like pretty detailed research involving a computer programme analysing over 47,000 movies.
* highlights the ones I have seen. Those highlighted in red, I might seek out. But pleased to see many old friends in there, especially Citizen Kane, Casablanca and The Searchers.
The more I study the list the more I think it is hard to disagree with it, although we would not all have the same personal top 20 list. And that's how it should be, of course.
