The entertainment industry is a funny place, one with its own set of rules. And one that has happened countless times over the years is that oftentimes the actors playing teenagers are a little long in the tooth to be doing so. Some of these performances are beloved, and others are infamous. There are particularly 32 actors that were way too old to be playing teens but did it anyway. And if you ask me, each performance on this list is pretty iconic.

Working with actual teenagers is tricky, unless the actor is emancipated and able to deal with the long hours usually required for TV and film work. So it's definitely understandable that production have chosen actors who were too long in the tooth to play their respective roles. In no particular order, here are the infamous 32.

Rachel McAdams in Mean Girls

Rachel McAdams, Mean Girls

You can't think of Rachel McAdams without her performance as Regina George in Mean Girls. While the cast of Mean Girls was mostly age appropriate, McAdams was actually 25 years old when playing the queen of the plastics. Still, I can't imagine anyone who could have played her better.

Stockard Channing, Grease

Grease is a beloved movie musical, one that I actually think improves upon the stage musical of the same name. While it's full of iconic performances, a lot of of the cast is  a bit too old for their roles. That includes Rizzo actress Stockard Channing, who was 33 years old. Regardless, she is THE Betty Rizzo, and she absolutely crushed the role.
