VIDEO : Matt Damon Says Robin Williams Made Him and Ben Affleck Cry

One of the most emotional on-set moments for Matt Damon came courtesy of Robin Williams. Damon and childhood friend Ben Affleck co-wrote and co-starred in the 1997 drama film Good Will Hunting, which featured Williams as Damon's title character's therapist. In an interview with E! News carried out before the film's release, Damon recalled how Williams made him and Affleck cry tears of joy. He said, "It was the very first day of shooting and Ben and I went to the set. We weren't working that day and we just saw them rehearse and we were kind of sitting off to the side of the camera...by the time they said, 'Action,' tears were just falling down my face. I couldn't believe it. I was just looking at Robin start to speak and say these words that Ben and I had just worked on for five years."
