Christopher Reeve
Christopher ReeveUndoubtedly the most famous and iconic Superman, Christopher Reeve was the ultimate macho-man. The 1978 Clark Kent refused to wear fake muscles for the role, so the once skinny-boy trained with David Prowse, weightlifting champion and the man behind the ominous Darth Vader mask. After two intense months of a non-stop exercise regimen and doubling his calorie intake, Reeves put on 30 pounds and became the hunkiest man in Hollywood. [Photo via]
