The cinema verite style ambush scene is enough to recommend the movie.
How'd they do that?
The track marks of my movie habit.

I remember being disappointed by this movie when I was a kid, because the print ads had led me to believe it would be non-stop action - Lee Marvin and Ernest Borgnine, armed with hammers, chasing each other across the top of a moving train - and it turned out to be mostly talk.
