Kevin Costner | $250 Million | Businessman

Hollywood personality Kevin Costner placed some investment money on a company called Costner in Nevada Corporation or more popularly known as CINC Inc., back in the 1990s. While this didn’t make the news back then, things started to change when an oil spill happened in the Gulf of Mexico in 2010. His company was quiet for decades, but suddenly, he said he wanted to help. This act brought him on Good Morning America, where he told everyone where he was coming from.

He said that when he saw the situation and knew he could do something about it, he decided to act on it. Though he offered his 32 centrifuges to clean up the oil spill, authorities did not use them due to some delays. He managed to get attention for his company, though, so at least he got publicity.
