Top 5 - Movies Based in Massachusetts

1. JAWS
2. Good Will Hunting
3. The Thomas Crowne Affair (w/ Steve McQueen)
4. The Verdict
5. (tie) The Paper Chase (tie) The Boondock Saints

The Perfect Storm, The Brinks Job and The Last Hurrah almost made the list but I gave no consideration to Love Story.

The idea for this list came from a list of the top movie set in each state by Steve Silver (which I found via BST)
