These are the ~500 most famous people, by number of Wikipedia languages, who are primarily known as actors and actresses. How many can you name in 15 minutes, without any hints?
Tip: just spam all that come to mind
Some surprising inclusions and omissions, I'll admit, but this is an objective method
Most of these are Hollywood actors
Criterion for whether someone in known *primarily* for acting is mostly the Pantheon, but in some cases I overruled it based on personal judgement
The challenge here is not how many of them you know, but how many come to mind in a relatively short time. Even if I increased the time to an hour, people would not remember all the actors they know, and also I want people to take the quiz even if they have less time available.
