7. Leonardo DiCaprio – Sci-Fi Figurine Collecting
Leonardo DiCaprio is apparently a huge Star Wars fan, and that was brought to the spotlight when he auctioned hundreds of vintage figurines perfectly maintained in their original packaging. His auction even included characters from E.T., Planet of the Apes, 2001: A Space Odyssey and The A-Team. The auction was to benefit the Leonardo DiCaprio Foundation for environmental protection.
