Hidden ending:

When the credits appear, advance to the end. There are about ten to fifteen minutes of credits before they fade away. A scene of Dominique driving an old Chevelle SS in Mexico, where he fled to, will appear. He repeats his saying earlier in the movie of "I only live life a quarter of a mile at a time. And for those 10 seconds i am free..." as he drives off on an empty trail in Mexico into the sun. You cannot skip directly to this because it does not have its own chapter stop
