Ben Affleck Once Injured Matt Damon on Set — A School Ties Moment They Still Laugh About

Hollywood best friends Ben Affleck and Matt Damon recently shared a funny but scary memory from their early acting days that happened while filming the 1992 movie School Ties. The story came out during a recent interview while they were promoting their new film.

The two actors appeared together on The Tonight Show Starring Jimmy Fallon, where host Jimmy Fallon asked them about an old on-set accident that involved an acorn. What followed was a moment full of laughter and honesty, showing just how long their friendship has lasted.

Matt Damon explained that they were very young, around 19 or 20 years old, when they were filming School Ties. Between takes, the cast — which also included Brendan Fraser and Chris O’Donnell — had a lot of free time. Like many bored teenagers, they started throwing acorns at each other while walking around the school campus where the movie was being shot.

During this playful moment, Ben Affleck threw an acorn toward another actor. That actor moved out of the way, and the acorn accidentally hit Matt Damon directly in the eye. Matt said the impact was serious enough that he had to be taken to the hospital, where doctors gave him an eye patch to wear for several days.

Ben Affleck admitted that while he felt bad for his friend, his first fear was something else entirely. He worried that he might get fired from the movie, especially since he had only a few lines in the film. At that time, both actors were just starting out, and losing a role could have changed everything.

Thankfully, Matt recovered fully, and the incident did not affect their careers. Today, both actors look back on the moment as a lesson from their youth and something they can now laugh about together.

The interview happened while Ben and Matt were promoting their new movie The Rip, which is set to release on Netflix. The film is directed by Joe Carnahan and is inspired by real-life events involving crime and hidden money.

This story shows that even the biggest stars have awkward and risky moments from their early careers. More importantly, it highlights the strong bond between Ben Affleck and Matt Damon — a friendship that has survived accidents, decades in Hollywood, and many films together.
