If everything goes right on a film set, you'll never see a mistake in the final cut.

But sometimes a mistake becomes a happy accident. An actor flubs their line in an amusing way, or they get so into the performance that they break something — possibly even a bone. The resulting shot might just be too effective to leave on the cutting room floor. (Just ask Viggo Mortensen.)

It's incredibly rare, but several directors, including Quentin Tarantino and Mike Nichols, have included such blunders — some of them that look quite painful! — in the finished versions of their films. Here's a look back at eight movie mistakes that made the final cut.

Django Unchained

*Django Unchained* (2012) wasn't an easy shoot according to several cast members, including Kerry Washington, who told *The Hollywood Reporter* she "had nightmares" from filming a harrowing scene in a metal box. Her costar Leonardo DiCaprio didn't escape the production unscathed, either. The bloodied, bandaged hand that his character, villain Calvin Candie, sports in the third act of the film was the result of a real injury.

In one of the more memorable scenes in Quentin Tarantino's western, Candie goes on a vile, racist rant and slams his hand on a table, shattering a glass. "It disintegrated into his hand," said producer Stacy Sher, "and he never flinched." DiCaprio recalled that his "hand started really pouring blood all over the table," but they continued filming the scene.

The crew erupted in applause afterward, and Tarantino decided to use that take in the final cut.

The Usual Suspects

Kevin Pollak, Stephen Baldwin, Benicio Del Toro, Gabriel Byrne, and Kevin Spacey in 'The Usual Suspects'.

There's a famous scene in the 1995 thriller *The Usual Suspects* when the five criminals — played by Kevin Pollak, Stephen Baldwin, Benicio Del Toro, Gabriel Byrne, and Kevin Spacey — are finally assembled in one room for a police lineup. One at a time, each man steps forward to recite the incriminating line, but when it gets to Del Toro, he starts laughing uncontrollably, which makes the other actors laugh as well.

According to screenwriter Christopher McQuarrie (in a since-deleted tweet), the laughter was real — the result of *someone* in the room having gas. "[O]ne of the actors broke wind in a very hot and confined space (I have the outtakes in which it's audible)," McQuarrie wrote. "The more they were directed to play it straight, the more they laughed."

The screenwriter credits editor John Ottman, who "saw the value and left it in." The only question that remains is: who dealt it?

We all know *Grease* is the word in the 1978 musical's titular song, but on one particular day of filming, the word was... gumdrops.

Early in the film, Danny Zuko (John Travolta) and his T-Bird pals are clowning on the school's football players when Barry Pearl's Doody calls them "gumdrops." As Pearl recently explained, that was actually a flub — he meant to say "gavone," an Italian word for someone who is ill-mannered or sloppy, which he learned from costar Michael Tucci.

"I loved that," said Pearl, who added that the cast "did a lot of improvisation in many of the scenes." After Tucci said "gavone," Pearl tried — and failed — to mimic him. "At that point, I already had the 'G' coming out of my mouth. So, I said, ‘Gumdrops, man,'" recalled the actor, who admitted that the word was nonsensical. "It’s not a put-down, it’s nothing! And that’s the shot that they’ve got in the movie."

The Lord of the Rings: The Two Towers

New Line Cinema

You've probably seen the meme: Viggo Mortensen, as Aragorn in *The Lord of the Rings*, angrily kicks a helmet and screams at the sky. That anger is as real as the toes he broke while filming the scene.

The moment occurs in *The Lord of the Rings: The Two Towers* (2002), when Aragorn thinks two of his comrades are dead. In a behind-the-scenes feature included on the physical release of the film, director Peter Jackson explained that he made Mortensen perform several takes. After the fourth take, Jackson said, "I thought, oh, look, he's got better each time. If I just give him one more take, I bet it's gonna look great."

"So he boots this helmet, and then he let out this scream," which Jackson thought was just the actor giving an incredible performance. Later on, Jackson found out that Mortensen broke two toes when he kicked the helmet on that final take, which was so good that Jackson kept it in.

Patriot Games

When future *Game of Thrones *star Sean Bean was cast in *Patriot Games* (1992), it was the actor's first role in a big studio film. Bean played the villain in the Tom Clancy adaptation, which stars Harrison Ford as your dad's favorite protagonist, Jack Ryan. According to Bean, the movie scarred him for life — literally.

In an interview with Josh Horowitz on the *Happy Sad Confused* podcast, Bean recalled filming the climactic brawl, which takes place on a boat in the pouring rain. At one point, Ford slashes Bean's face with a boat hook — and, as it turned out, that actually happened. "I think he just slipped and he, you know, caught me with this boat hook right across here," said Bean, gesturing to a spot over his left eye.

Bean initially didn't realize how badly he had been injured. The wound ultimately required 35 stitches.

Nightcrawler

Jake Gyllenhaal in 'Nightcrawler'.

Open Road Films

Jake Gyllenhaal gave one of the best performances of his career in the 2014 thriller *Nightcrawler*, in which he plays an opportunistic criminal who becomes an ambulance chaser so he can sell sensational footage to a local news station.

In one of the film's most unnerving scenes, Gyllenhaal's character rages out in front of his bathroom mirror. He slams and then punches the mirror, shattering it. As Gyllenhaal recounted on the *Ellen *show, he really broke the mirror and injured himself in the process.

"It hit a mirror and it broke, and it cut my hand," he said to host Ellen DeGeneres, who asked, "What do you mean 'a mirror broke'? Did you punch it?"

"No, I looked at it really hard," the actor joked, and offered to show DeGeneres his "really gross" hand, which was still healing from the injury. Gyllenhaal, who was also a producer on *Nightcrawler*, confirmed that they decided to keep the shot in the film.

The Birdcage

Robin Williams, Hank Azaria, and Dan Futterman in 'The Birdcage'.

*The Birdcage *(1996) is absolutely *stuffed* with hilarious moments — no surprise given the comedic talent involved. Directed by Mike Nichols and written by Elaine May, the film stars Robin Williams and Nathan Lane as a couple who pretend they're straight to make a good impression on their son's soon-to-be in-laws, with the help of their housekeeper, played by Hank Azaria.

During a memorable sequence, Williams and Azaria's characters are frantically running around the kitchen when Azaria slips and falls. Moments later, Williams *also* slips and falls. According to Azaria, that moment was not in the script.

"That was absolutely not intentional," Azaria told *The A.V. Club*. "And if you watch that little piece of film again, you’ll see me laughing and Robin laughing. It’s one of those things that happens that you never really think they’re going to use, but I was so emotionally upset in the scene — I was supposed to be crying — that I just pretended that he was making me cry even more. But I was actually laughing."

Macaulay Culkin in 'Home Alone'.

20th Century Studios

It's probably the most iconic image from *Home Alone* (1990): Macaulay Culkin standing in front of a mirror, eyes wide, screaming with his hands clapped on either side of his face. In the film, young Kevin McCallister — accidentally left home alone on Christmas by his parents — is using his dad's grooming products and has a hilarious reaction when he slaps on the aftershave.

Director Chris Columbus later revealed that the scene wasn't supposed to play out like that. "He was supposed to put the aftershave on, put his hands to his face, and immediately remove his hands and then scream," said Columbus. "That was the direction I gave him on the first take, and he kept his hands there. For whatever reason, I don't know."

He continued, "Maybe he was nervous. He just didn't move his hands from his cheeks and it made all of us laugh. Now usually when the crew laughs, it means it's not funny. But the crew laughed, and we kept it in the first preview of the film, and the audience loved it."
