20 times actors broke on screen, and it stayed in the final cut

In a hilarious end scene in Friends , while David Schwimmer is playing the bagpipes, Lisa Kudrow joins in and sings along. The antic made Jennifer Aniston break out laughing, and audiences can see her laughing in the episode. 

In a later episode of Parks and Recreation , Amy Poehler expertly delivers the line “You have five seconds to get out of here, or I will rip your throats out.” Understandably, Adam Scott couldn’t keep it together, and he had to adjust his face to keep from laughing. 

In a hilarious scene in Wayne’s World, Dana Carvey improvised a line where he asked if Mike Myers’ character ever saw Bugs Bunny as a girl. Myers found the line hilarious, and his honest reaction made it to the final cut. 

How any scene in Arrested Development ever got filmed is a mystery. When David Cross said to Jason Bateman, “And secondably, I know you’re the big marriage expert. Oh, I’m sorry, I forgot. Your wife is dead,” you can see Bateman crack a smile. 

Murderville was mostly improv, so lots of guest actors broke. But Kumail Nanjiani did the impossible by making the show’s star Will Arnett break by squawking when being asked what his signature sound is. 

In an episode of Will & Grace, Debra Messing breaks when having a dialogue with Sean Hayes about his character being “a woman of quality.” In fairness to Messing, Hayes broke in the scene, too. 

The Fast & Furious actors have spent so much time together that, at this point, they’re just having fun while filming. In the sixth film of the franchise, Ludacris told Dwayne “The Rock” Johnson to say the line “You better hide that big ašs forehead” to Tyrese Gibson. The rapper didn’t think The Rock would do it, and his genuine reaction to the delivery was left in the film. 

Julia Louis-Dreyfus was so funny in Veep that she made herself break. After her iconic line delivery of “That’s like trying to use a croissant as a f—ing đildo,” Louis-Dreyfus nearly lost it herself. 

In a scene in Harry Potter and the Order of the Phoenix , Emma Watson tells Rupert Grint that his character has “the emotional range of a teaspoon,” which caused those two and Daniel Radcliffe all to crack up. Watson was especially tickled by the moment. 

While filming Pretty Woman , director Gary Marshall told Richard Gere to hit Julia Roberts’ finger with the jewelry box he was holding. Roberts didn’t know about the direction, and her laugh from being caught off guard was left in the film. 

In a touching scene in Good Will Hunting , Robin Williams improvises dialogue about his character’s late wife. Naturally, Williams’ lines were hilarious, eliciting laughter from Damon that was kept in the film. 

Actors have been breaking on screen for decades. In Dr. Strangelove, Peter Bull struggled to keep it together for an entire scene with Peter Sellers. He finally breaks, and his laughter is in the final edit. 

Bob Odenkirk is so funny that he can make actors break even when they expect a line from him. In an episode of Better Call Saul, Rhea Seehorn cracked up at Odenkirk’s delivery of “Wait ‘til you see what I floss with,” and her reaction stayed in the show. 

In Sister Act, Whoopi Goldberg can be seen laughing in response to a sound from Dame Maggie Smith. When Smith said “Come in,” she also let out a surprising noise that Goldberg couldn’t help but react to. 

In an episode of That ‘70s Show, Debra Jo Rupp’s character accompanies the younger gals to a strip club. Mila Kunis couldn’t handle Rupp’s hilarity, and her laughter was left in the final edit. 

In Dumb and Dumber , Jim Carrey lets out “the most annoying sound in the world,” much to the chagrin of Mike Starr and Jeff Daniels. Both Daniels and Starr nearly lose it, and their fight not to laugh is evident in the film. 

In all fairness, it would be impossible not to break on the set of It’s Always Sunny in Philadelphia . In one scene that takes place at a courthouse, Charlie Day’s character is trying to give Glenn Howerton’s character some papers. Howerton refuses them, and the interaction made Day laugh so much that he had to look down to keep from totally losing it, and it all was caught on camera. 

Tonally, it doesn’t work for breaks to be left in The Office , but a few snuck their way in. In a scene where Steve Carell’s character accused Paul Lieberstein’s character of being a flasher, John Krasinski nearly loses it in the background. He covers his mouth to keep from laughing, and the moment can be seen in the episode. 

Another break that snuck its way into the final cut of The Office was guest star Idris Elba nearly losing it at Brian Baumgartner’s character saying “Hi” in the most earnest way possible, about three seconds too late. It was too good not to stay in the episode. 

And because it’s too good not to point out the times actors broke on The Office, one of Mindy Kaling’s breaks stayed in the final cut, too. In a Christmas episode, the actor couldn’t keep it together when Brian Baumgartner sat on Steve Carell’s lap. We wouldn’t have been able to keep a straight face, either.
