This is my favorite of all the twilight zone episodes. The story of two men struggling to make a living in a time in the not-to-distant future, and not doing very well. The sport of boxing has been ruled too brutal for humans to engage in, and so it is now done only by robots. Lee Marvin and his pal field a robot, who after many bouts is falling apart and can't go any longer. But the two men have bills to pay, and have to field an entry in tonight's match. The opponent is the latest, newest, strongest model fighting machine robot - a truly frightening prospect. And guess who has to go up against it. This turns into a memorable tale of guts, determination, or just call it heart.
