I saw this as a 4 hour movie on UK tv. As it was based on a true story I found it very interesting and most of the 4 hours seemed to go very quick - although some bits did seem to drag on. The acting is excellent in most places and it's fun to see big names back before they were famous (Macy, Gallagher and Spacey). William H Macy doesn't really do very much, Spacey hangs around and does well enough, Lemmon is great but Peter Gallagher does better than I've ever seen him be as the manager of the factory where the murder occurs.
All in all, a well acted story that manages to keep you interested but over one 4 hour sitting can be quite hard work at times.
