1. James Cameron
James Cameron – number one on our list of 18 most famous atheists in the world doesn’t need introduction. Everything this man has touched has turned to gold. He has only failed to win an Oscar for Leonardo DiCaprio, but Leo will get there. Eventually. Though, James Cameron has won plenty of Academy Awards, Golden Globes, and Primetime Emmy Awards. He’s somewhere in between agnosticism and atheism when it comes to his religious views. “I’ve sworn off agnosticism, which I now call cowardly atheism. I’ve come to the position that in the complete absence of any supporting data whatsoever for the persistence of the individual in some spiritual form, it is necessary to operate under the provisional conclusion that there is no afterlife and then be ready to amend that if I find otherwise.” Well, more like agnostic, but I just had to put him on the list.
