The famous Midnight Cowboy scene where Rico slams his hands down on a taxi that almost hits him and yells “I’m walking here!” was the result of an accident. They didn’t have the money to create a full set with extras, so they used a “stolen shot” — using a hidden camera on a real street. At one point the characters cross the street — they had rehearsed and timed the dialogue so they could cross when the signal was green. But in the first shot, a car ran the light and almost hit them. Staying in character, Rico yelled, “I’m walking here!”

Costar Hank Azaria revealed that Robin Williams’ fall in The Birdcage was accidental. “If you watch that little piece of film again, you’ll see me laughing and Robin laughing.

But I was actually laughing.”

Screenwriter Krysty Wilson-Cairns said she screamed when he fell, and that it was like “watching your team mess up a field goal at the Super Bowl.” When George MacKay got up, director Sam Mendes yelled to keep filming, “and out of that came a sort of movie magic, I think, personally,” Wilson-Cairns said. “I’m obviously a little biased, but it’s one of my favorite scenes of the film.”

The famous shot of Daniel Craig as James Bond walking out of the water in Casino Royale was not meant to happen. “It was actually by accident,” he said. “Where we filmed, off the Bahamas, it’s just one of those places where there is a sand shelf and the sand shelf happens to be three feet deep. Because the idea was, I was supposed to swim in and sort of float off, but I swim in and stand up. And it was just one of those things.”
