Director Joel Coen's and producer Ethan Coen's "Blood Simple ("1984, River Road Prods/Circle Releasing/Palace) is a contemporary noir thriller set in Texas. A taut, convoluted plot and imaginative direction made the independent release a word-of-mouth hit and established the Coen brothers' reputation for originality. Actors John Getz, Frances McDormand, and Dan Hedaya appear in the story in which a woman commits adultery, and her enraged husband hires a killer for revenge. Blackmail, violence, and mistaken assumptions lead to an edgy, exhilarating climax.
