By now, Se7en has become one of the most beloved thrillers of the 1990s. But did you know that in the big chase scene in the rain, Brad Pitt really fell and severely hurt his arm? The injury was so serious Pitt required surgery, and he had to spend the rest of production with his arm in a cast. The broken arm was written into the script, but you might notice that Pitt spends a lot of the film hiding his arm behind various objects — because those scene were shot after Pitt broke his arm, but they took place in the movie before the chase. That’s just one of the facts featured in the newest episode of You Think You Know Movies!

Before he became a movie star, Pitt attended the University of Missouri, where he majored in journalism with a focus on advertising. He dropped out of school two credits shy of a degree to move to Los Angeles and pursue a career in acting. At the time, he had just $325 to his name, and he wound up sleeping on the couch of another up-and-coming talent: Melissa Etheridge.
