Paxton passed away from the complications of a surgery earlier this year. He had collaborated with Cameron on projects like "True Lies" and "Titanic".
When asked about why Paxton did not feature in "Avatar", Cameron told Entertainment Weekly, "I don't remember what happened there. I don't think there was a part that fit him well. Otherwise, I would have loved to have him involved. And of course recently, I was staring down the barrel of four more Avatar films and I was thinking of a good place, a good fit for Bill."
