Actors Who Play Teenagers

I always find it hilarious when Hollywood tries to cast high school-themed movies or TV shows.  They always seem to cast an actor or actress who looks like they are a teenager but in reality, they are actually closer to 30 than they are 20.  The best example is the original Beverly Hills 90210.  Gabrielle Carteris (she played Andrea) was 29 years old when that show started which meant she was 39 when the show ended, you know, a show about kids in high school and yet she would have attended her 20th High School Reunion by the time that show finally over.  Hell, Luke Perry was 25 when that show kicked off.  You would think that Hollywood would have figured out a way to fix this ridiculousness, but no.  So, here are some more modern and hilarious ages of actors or actresses on high school-themed shows and movies (and no, I will not be checking every cast member of each show, just the ones that I know are way older than the character they portray):

Glee

• Lea Michelle - this manly-looking woman was already 23 when Glee's pilot hit the air and is now 27 playing a college freshman (I think that's right, I'm basing that off of the commercials, I swear).
• Cory Monteith - I assume he plays a gay guy and he was 27 during the first season.
• Mark Salling - another 27 year old (presumably gay dude).

Friday Night Lights

• Taylor Kitsch - the awesome Tim Riggins was a 25 year old playing a 16 or 17 year old.
• Zach Gilford - he was 24 while portraying a sophomore back-up quarterback.
• Minka Kelly - the hot high school cheerleader was already 26 in the first season.
• Scott Porter - you know, the guy who was paralyzed in the first episode was a 27 year old senior.

The O.C.

• Ben McKenzie - this troubled high schooler was cast with a 25 year old actor.
• Rachel Bilson - this hottie was 22 when the show kicked off.
• Adam Brody - the high school comic relief actor was 24 in the first season.

American Pie

• Shannon Elizabeth - an actress that needs to get naked more often was 26 in this high school comedy.
• Sean William Scott - Stifler was already 23 years old when cast in this movie.

Fired Up!

• Nicholas D'Agosto - this movie is actually funny despite being about a cheerleading camp, also this actor was 29 when he played a high school senior.
• Eric Christian Olsen - by far the worst offender of the group and the reason I made this post, he was already 32 years old and playing a teenager when this movie was made.

"Yeah, this guy played a high school kid only 3 years ago.  Shenanigans!!!"
