Director James Cameron has reached the Earth’s deepest point, in a solo journey to explore a place only two men have gone before.”Just arrived at the ocean’s deepest pt. Hitting bottom never felt so good. Can’t wait to share what I’m seeing w/ you,” tweeted the director of “Titanic” and “Avatar,” from his state-of-the-art diving vessel Deepsea Challenger. @Yungjohnnybravo @TatWZA
