James Cameron is already putting into action a life-long dream to dive to the deepest part of our oceans — and now it appears that he may soon also fulfill a desire to explore the heavens as well. 

The 56-year-old "Avatar" director is rumored to be in possession of a $150 million ticket to fly around the moon and back. The entire journey would take 17 days and include a stopover on the International Space Station (ISS). The Virginia-based Space Adventures, which has arranged every privately funded trip to the ISS, is selling two seats on a Russian Soyuz spacecraft being designed for lunar orbit. The firm recently revealed that one "high-profile client" had reserved the first spot — with The Sunday Times of London leaking that Cameron is the mystery buyer.
