What are some things that happen in movies that most people think are bullshit, but are actually true?

I don't know if this is something people would "call bullshit" on, but it's a pretty cool moment captured on camera.

In Quentin Tarantino's Django Unchained, Calvin Candie (Leonardo DiCaprio) confronts Django (Jamie Foxx) and Dr. Schultz (Christoph Waltz) in arguably the most climactic scene of the entire movie. In a fit of rage, Candie slams his hand down on the table and accidentally crushes a wine glass, leaving a large gash in his hand. Without breaking character, DiCaprio finishes the scene with copious amounts of his blood dripping down his hand and arm. He even rubs the blood on the face of Broomhilda von Shaft (Kerry Washington) to her horror, quite understandably.

After reviewing the takes, the one mentioned above was selected for the final cut (no pun intended). He later received stitches for the wound and mentioned it during several interviews.

Whenever I watch the movie, I wait for that scene in anticipation and am awed by the dedication of DiCaprio to his character as well as the reactions from the rest of that incredibly talented ensemble.
