You see these Hollywood leading men on the big screen, but do you know which one is the same age as you? It can be hard to tell, thanks to makeup and a generally lavish lifestyle, but PrettyFamous found the most famous actors aged 17 to 86 (as of September 2016).
Within each age group, they determined the most famous actor by calculating their "Actor Score" on a scale from 0 to 100 that takes into account a) the number of awards the actor has been nominated for, b) the total number of IMDb ratings for films and television shows they had roles in, and c) recent interest, as determined by Wikipedia page views over the past 30 days.
It just goes to show that talent knows no age or bounds!
