In funny movies, it’s hard to keep a straight face. That goes double when the actors are so funny themselves, they crack each other up. Most of those shots get deleted and put into a pile where they get combined for bloopers or outtakes that viewers get to watch later.

But sometimes, they make the shot. Directors may not notice that a person is laughing when they shouldn’t be. Sometimes, that kind of thing can get mixed in the cutting of the movie and it stays in. That’s when it becomes an iconic mistake that reviewers get to talk about later.

Other times though, directors purposely leave bloopers in a scene. When you run the scene back a hundred times and it doesn’t get any better, sometimes it’s just best to leave it in there because it’s the best shot they have.

Laughing in a funny scene can make the scene. These scenes definitely were made better by the fact that the actors couldn’t compose themselves. There was just too much going on and it wasn’t going to happen. So, the director stuck with it and these have been some of the most iconic scenes in cinematic history.

Transylvania 6-5000

Michael Richards plays an odd ball Bellboy who has some of the weirdest quirks anyone can imagine. Jeff Goldblum can hardly compose himself. But, Richards works hard and even gets Ed Begley Jr. to crack.

The 40 Year Old Virgin

Steve Carell does a shot where he is getting his hair ripped from his chest. The thing is he is actually getting hair ripped from his chest. Everyone else in the scene is just reacting naturally to the sounds of horror coming out of Steve.

Anchorman 2: The Legend Continues

In a total improv moment, Will Ferrell is doing his warmups for the next news broadcast. He is so obnoxiously going off that no one can keep their composure. Christina Applegate tries, but she fails miserably.
