Whoâ€™s more famous? That question led to this site. Famousr keeps track of over 8,000 actors, calculating a â€œfame rankâ€ from a variety of data sources, including: mentions online, on blogs, and in the news, as well as the popularity and volume of movies/shows they were featured in. The algorithm tends to favor current actors (famous NOW), big budget movie actors (Tom Cruise), and press-worthy actors (Paris Hilton, sadly). It in no way signifies the quality of the actor!
Basically you just click on who you think is more famous and see if you guessed right.
