 GEOG: The final car crash scene occurs near Boston Common on the  corner of Joy and Beacon Street, as the car comes out of Joy onto  Beacon. While it appears that much of the footage was filmed on Joy  or adjacent streets, it could not have happened the way it did in  the movie. Joy Street is only about a quarter mile long, and all but  the final half block (shown correctly in the movie) is uphill when  going toward Boston Common. This would obviously ruin the plot line  that they couldnt apply the cars brakes. It appears footage was  taken of Joy traveling in the opposite direction, as well as  adjacent streets to mix up the scenery.
