Do You Know, Cory Monteith--who plays the 17-year-old Quarterback--Is Really 27?

Most actors play roles that are not their age. It is rare to have television shows with teenagers acting like teenagers, one of the reasons is their work contracts, but another is a lot of actors that play these roles play them year round which would mean that their school work would suffer, the fact that most have graduated from college acting courses also adds to it. That being said with the exceptions of Chris Colfer and Kevin McHale who are 21 and 23 respectively the rest are in their mid to late 20s, funnier is that Matthew Morrison is just 4 years older then both Cory and Mark Salling. Other shows with weird ages but the weirdest I remember my cousin going on about was with a show that had Betty White, The Golden Girls, supposedly Sofia (Mother) was a year younger then Dorothy (Daughter). For me a major age misstep I noticed was in Alexander with Angelina Jolie playing Colin Farrell's mother, because they are so well known it is impossible to not see that the age is all wrong.

I remember looking at Luke Perry and thinking, I know he's supposed to be in high school, but his hair line is receding! I always thought it was so funny that he was so much older than the character he played. I watch The Vampire Diaries, and the actor Paul Wesley who plays Stefan is supposed to be stuck in the age of 17. But the actor is 28. I don't know that I've ever seen a 17 year old look quite that good.
