I saw this movie on TV back in 1978, and though I have never seen it again, it made a deep impression. Its originality, in addition to being just about born a die-hard fan of Johnny Cash, made it a must-see.
Johnny Cash makes one of his very few real performances with more than historical interest. Both men get themselves involved in a bet-on gunfight. They decide to meet on the local arena like wild-west gladiators. However, a special friendship starts growing between two rivals set up to kill each other. The end of the story leaves us thoughtful.
Why this movie has been so much overlooked is a mystery to me.
