A strange world we live in where people obsess about figures in popular culture.
I don't know if you mean "world" literally -- as in, the entire human species -- or the world of modern developed countries where people might be interested in Jeremy Renner or Ben Affleck. But I think of it in the former sense, as something that happens in every culture. In the absence of mass media or widespread mobility, where people would live in villages or towns or tribes, often seeing the same smallish group of families and neighbors throughout their lives, people would obsess about -- their local versions of celebrities. The chief or mayor, the successful warrior, the handsome butcher and so on. That wold be a far smaller group, of course, than the thousands of celebrities modern people obsess about, with our access to images and information involving strangers all over the world whom we will never meet in person.
Interesting topic on a site specifically offered for people who are literally obsessed with one particular item of popular culture (well, two items), both in fictional and real-life ways. And with a group that for months has been playing a fun game based on real-life figures people obsess about, mostly entertainers!

Wait -- have we done Ben Affleck yet?
