Matt and Ben have been buddies ever since they were kids growing up in Boston. Long after the actors co-wrote and co-starred in "Good Will Hunting" and enjoyed success, marriage, and children, they remained close as ever. When Ben found out that Michael Douglas kissed his buddy during filming of "Behind the Candelabra," he said, "It burns me up. You know, I feel the envy in my heart. I can't stand it."
