One of my all-time favourite movies, and probably Tony Scott's shining moment. I watch it again every couple years -- couldn't get enough of it when I first discovered it (which was about 10 years ago).
I love that scene between Walken and Hopper, brings a tear to my eye every time.
And Bronson Pinchot is great in it. Such a nice contrast to the character he played in Beverley Hills Cop.
