A remake of the 1931 film of the same name, Iron Man stars Jeff Chandler as up-and-coming boxer Cokie Martin. A relatively pleasant fellow outside the ring, Martin turns into a monster whenever he dons boxing gloves and trunks. As a result, he becomes "the man you love to hate" so far as the fans are concerned. Only his fiancee Rose (Evelyn Keyes) is willing to stand by him, but even her devotion is sorely tested when Cokie continues displaying his killer instinct. Only the intervention of "clean" fighter Speed O'Keefe (Rock Hudson) prevents Cokie from destroying himself. Told in flashback, Iron Man is at its best in its expository scenes, showing the hero working his way out of a coal mining town and into the championship. Joyce Holden co-stars as a good-time girl who enjoys a brief fling with the hero; in the original 1931 version, Holden's character was played by Jean Harlow.
