Avatar 4, James Cameron Does Not Give Up: Hiroshima Will Be Released Before Avatar 4

While we are thinking about the filming of Avatar 3, director James Cameron is largely moving forward with the times thinking of a now-dated project: Hiroshima.
James Cameron does not seem to want to give up on his idea of making the film adaptation of The Last Train From Hiroshima: The Survivors Look Back, a book by Charles R. Pellegrino.
The book focuses on a World War II scenario, especially the cities of Hiroshima and Nagasaki, taking the point of view of the survivors of the bombings. Already in 2010, Cameron spoke of this adaptation, so much so that the director had interviewed Tsutomu Yamaguchi, the only survivor of both bombings. However, the survivor sadly passed away the same year, before any film adaptation.
But Cameron does not give up and would seem to want to make it before the fourth chapter of Avatar. The director said for the LA Times that: ” Today we live in an even more precarious world than we believed. I think the Hiroshima film would be even more topical than before. It reminds people what weapons are capable of doing if they are used against humans themselves .” For the director, it would therefore seem to give precedence to this project before concluding Avatar 4 as well.
