Good Will Hunting Ending Exlained: What "He Stole My Line" Means

The famous last line in Gus Van Sant’s Good Will Hunting is even more memorable due to one key factor. At the end of the movie, Sean (Robin Williams) reads a letter from Will (Matt Damon) that he “has to go see about a girl”, a phenomenal callback to a previous conversation between Will and Sean earlier in the movie that created a unique and profound full circle moment. The perfect ending to Good Will Hunting was surprisingly not written in Van Sant’s script and was one of the many creative contributions of Williams, whose brilliance shone throughout the film as the wise mentor to the troubled genius Will Hunting.
