#9 Franco Columbu
Net Worth: $10 Million
After Joe Weider encouraged him to come to America in 1969, Franco Columbu set a number of powerlifting and Olympic world records. He won four Mr. Olympia titles, three of which were in the lightweight category before the IFBB abandoned weight classes. Columbu placed fifth in his first World’s Strongest Man competition. What makes that such a remarkable feat is that he weighed much less than the bulk of his competitors.
Columbu also made minor forays into acting, appearing in several films with Arnold including Conan the Barbarian and The Terminator. He also appeared in many TV shows and commercials.
