6. James Cameron’s Submarine “Deep Sea Challenger”
James Cameron earned his fortune by directing several famous box office hits like Terminator, Aliens, Titanic, and Avatar. Before he filmed Titanic, Cameron acquired a $500 million submarine called the “Deep Sea Challenger“. This submarine was the first of its kind- a mobile underwater filming unit. But this isn’t just an expensive toy. Because of this submarine, James Cameron was able to film Titanic in a way that the story was never portrayed before. He has collaborated with National Geographic to film several underwater documentaries, as well.
This is an example of a wise business investment. What most people don’t realize is that Rolex and National Geographic also helped to pay for the creation of the submarine. But since he’s a famous Hollywood movie director, James Cameron gets all the credit. He currently has a net worth of $700 million, not including the sub.
