8 Huge Actors You Didn’t Notice As Extras In TV Shows

8. Christopher Lloyd - It's Always Sunny In Philadelphia

Christopher Lloyd, the legendary Doc Brown, co-star of Danny DeVito in Taxi, icon of the screen and an extra in It's Always Sunny In Philadelphia? Really? When on Earth was he in that? You'd think he'd be easy to spot. Well, his cameo seemed to fly over people's heads like Santa's sleigh itself.

The Always Sunny Christmas special was a hilarious look into holiday life as led by this gang of sociopaths. One of the most shocking - and hilarious - moments came when Charlie recalled his young Christmas days when multiple men dressed as Santa would come along, give him a present and "cheer" his mom up for a while. Yikes.

But, among the cascade of red-clad jolly men was an actor of high repute. During the montage of Santas arriving, one of them is, of course, played by Christopher Lloyd. It's easy to miss as his beard covers most of his face, but you'll never be able to unsee it once you spot it.

It's a hilarious cameo for sure. Still, you won't want to imagine the kind of things he did to Charlie's mom. Great Scott!
