After watching a new show or movie it isn't uncommon to go straight to Google and look up all of the new actors you've just discovered.
I've definitely done it before and sometimes I am VERY surprised.
For example, I can't be the only one who was surprised to find out that Darren Barnet from Never Have I Ever is actually 29 years old and not closer in age to his 16-year-old character Paxton Hall-Yoshida.
Or maybe you got so used to Paul Wesley playing an 17-year-old vampire (more like 171-year-old) in The Vampire Diaries that you forgot he was 27 when the show first started
Maybe for you, finding out that Andrew Garfield was 27 years old while playing 17-year-old Peter Parker in The Amazing Spider-Man was a shock.
Or maybe the fact that Gabrielle Union was 28 in Bring It On amazed you because she 100% could pass as an 18-year-old.
So tell us! We wanna know which adult actors played teenagers so well you sometimes forgot they were actually grown. The best responses could be featured in a BuzzFeed Community post or video!
