James Cameron – Triton

It is an understatement to call James Cameron a successful director, for he just directed what is considered the most successful film ever made, the classic romantic period drama Titanic. And, as if that’s not enough, he is also the man behind the hugely successful 2009 film Avatar, which recently surpassed the former with over $2 billion of ticket sales worldwide. He simply is the blockbuster king of Hollywood. He also has a wide array of investments under his belt, including a vineyard and a $2.7 million winery. With his massive wealth, he seems to enjoy a lavish lifestyle and buys luxury items like toys.

In fact, you might be surprised to know that most of the underwater sequences of James Cameron’s movies got shot using his own fleet of submarines. And his most priceless possession is the Triton Submarine, which he bought for a mind-boggling $3 million.
