Most Dangerous Man Alive [1961 - USA] atomic sci fi

En route to San Quentin and the gas chamber in being convicted of murder, gangster Eddie Candell, a publicity hound who laundered his illegal wealth through his vending machine company, is able to escape custody. Although not yet apprehended, Eddie is seen on surveillance footage stumbling onto a nuclear test site just as a test bomb is detonated, he subsequently seen surviving the explosion. Scientist Dr. Meeker, who has been doing tests on animals exposed to the primary nuclear fallout of Chemical X, is certain that iron has fused onto Eddie's internal body, literally making him a seemingly indestructible iron man. In this aftermath, four different groups or individuals are looking for Eddie, none who may be able to stop him from doing whatever he wants in his new physical state. First are the authorities led by Captain Davis and Lieutenant Fisher who just want him captured and his sentence completed. Second are his former criminal associates who framed him for this crime which he didn't commit. Top among these former associates who Eddie may be looking for in return to exact revenge are Andy Damon, who led the plot against him, and Linda Marlow, Eddie's girl who in reality was working for Damon in being truly his girl, her perjured testimony which clinched the conviction against Eddie. Third is Dr. Meeker, who solely wants to help Eddie. While unsure of the long term health effects to him or to others with who he is in contact, Dr. Meeker believes that the iron in Eddie's body will only intensify those criminal instincts inherent to him, that is unless there is some sort of medical intervention. And fourth is Carla Angelo, Eddie's protege who truly does love him and only wants to see that he is safe.
