According to IMDB, Robert Redford messed up at the very end of this six-minute-long continuous scene from All the President's Men. He accidentally calls the man his character Bob is speaking to on the phone with — Dahlberg — "McGregor." (This is the man his character was on the phone with earlier in the scene). Given the mistake would require the entire six minutes to be reshot, Redford quickly corrects himself and stays in character, playing it off as if Bob has actually gotten the name wrong. It works because Redford's character is so flustered in the moment, and his mistake seems natural.

Donald Glover revealed to Conan O'Brien that the scene in which his character slips in The Martian was an accident. "I get up, and I, like, just eat it, like, I slipped so hard," Glover told Conan. He said everyone gasped, but he kept going with the scene. "After the scene's done, [director Ridley Scott] comes up and he's like, 'That was great,'" Glover continued. "When you see me in the movie, and I eat it, that's really eating it." The funny moment fit his character's overcaffeinated shakiness in the scene.

Glover also said Scott once told him about a scene in another of Scott’s films, Thelma & Louise, where Daryl — Thelma’s abusive husband, played by Christopher McDonald — falls. According to Glover, Scott said the fall was unplanned and that he liked keeping moments like that in because they made the film feel more real.

A ton of falls onscreen are apparently unscripted, which makes sense. Another example is, reportedly, Forrest Whitaker's fall from the opening credits in Platoon. We can't 100% confirm, but given the shoot involved the young actors actually on location in the jungle in an extremely realistic and grueling shoot, it wouldn't be surprising.

Another one: According to IMDB, in the scene where Dallas (Matt Dillon) tries to come onto Cherry in The Outsiders, Dillon did actually fall off his chair. This was not in the script. You can actually see C. Thomas Howell looks right at the camera as he laughs.

The cat in this scene from Half Nelson wasn't meant to be there, star Anthony Mackie recalled to Entertainment Weekly. It had just wandered onto set. "Nobody knew where this cat was from. Nobody checked this cat," Mackie said. "Ryan [Gosling, his costar] picks up the cat, nuzzles it, and starts rubbing the cat. And I'm like, 'Yo, you're gonna catch something. That cat was nasty." Mackie improvised around the moment, telling Gosling's character not to bring the cat into his house.

One of Clue's most famous scenes, where Mrs. White says the famous "flames on the side of my face," was improvised by Madeline Kahn. "All that was written was, 'I hated her so much that I wanted to kill her,' or something like that," Michael McKean, who played Mr. Green, said. "But she just kind of went into a fugue about hatred. She did it three or four times, and each time was funnier than the last. I thought that they could have strung a bunch of them together because they had plenty of cutaways of all of us going, What the fuck is she talking about?" It's been rumored this is because Kahn forgot her lines, though it could've just been improv. (In which case, this one is less of an accident, but still a fun unscripted moment!)

The chase scene of The French Connection was way realer than you probably realized. "I had no permits to do the chase scene. None," director William Friedkin said. "I broke all the rules, I put myself in danger, I put the lives of others in danger, and I really didn’t care. I just felt that nothing was going to go wrong, and, by the grace of God, it didn't." He put a police siren atop the car to try to keep other drivers away, and operated the camera from the car while stunt driver Bill Hickman drove 90 mph. All car crashes and near-misses in the segment are real accidents (except the baby carriage stunt, which was staged). They actually had to give money to one disgruntled driver. This paid off; it's one of the best car chases in movie history.

Clint Eastwood's famous squinty stare, popularized in the movie that made him famous, A Fistful of Dollars, was accidental. "That was just the sunlight," Eastwood said when asked about his expression in his 1960s trio of films with Sergio Leone, which started with A Fistful of Dollars. "They bomb me with a bunch of lights, and you're outside, and it's 90 degrees. It's hard not to squint." The films were low-budget and shot in the hot deserts of Spain, so you can ha
