IMDb’s database contains more than 538,353 movies at the current moment. Of course, it’s impossible to watch all of them, and most of the films don’t even get viewers’ attention. But there are some movies that everyone has seen — us, you, our friends, and even our neighbor’s cat. And it’s pretty easy to find out whether a person really knows a particular movie masterpiece — in this case, its quotes turn into passwords we use, and iconic objects become some kind of reference point.
