Roberto Duran, Marvin Hagler, Ray Leonard and Thomas Hearns were involved in the last golden era of boxing: a time where proving to be the best around was far more important than losing an unbeaten record. These four warriors had some epic struggles between 1980 to 1989. Throw Wilfred Benitez into the mix and you had one of the best periods in boxing of all time. Duran: Brought up in great poverty, there was nothing he wouldn't do to provide for his family. This dark-eyed warrior liked nothing more than to inflict pain and suffering on his opponents in the ring: outside it, he was a good-hearted and generous man. Hagler: The mean, brooding middleweight felt the boxing authorities were against him from winning the world middleweight championship. The blue-collar champion, who would apply Vaseline to his own face and carry his own gym bag, reigned supreme for seven years, and to this day still feels aggrieved by his points defeat in his final contest. Leonard: The darling of boxing turned professional to the tune of $40,000, casting an envious eye on the more established practitioners. He had the knack of retiring for long periods and coming back against the odds. This charismatic man who faced boxing's best had to tackle his own personal demons outside the ring. Hearns: Not noted as a puncher in the amateur ranks, only to take the professional scene by storm, knocking out almost everyone he faced. he made history by becoming the first five-weight world champion. The Fab Four Part Two picks up exactly where Part One left off, exploring the rest of their explosive careers including the epic Hagler versus Hearns war right up to each man's retirement.
