Good Will Hunting is a 1997 film directed by Gus Van Sant and written by Matt Damon and Ben Affleck, both of whom star in the film.

Set in Boston, Massachusetts, it tells the story of Will Hunting (Damon), a troubled young Irish Catholic man from South Boston who, although a prodigy and autodidact, works as a janitor at the Massachusetts Institute of Technology, despite the fact that his knowledge of and facility with higher mathematics far outstrips that of anyone in the university. Will must learn to overcome his deep fear of abandonment in order to learn how to trust and love the people who care about him.

Good Will Hunting was a financial success, earned widespread critical praise and several awards, and launched Damon and Affleck into prominence.
