Guillermo Arriaga is going to write the script.
The film is based on the soon to be released nonfiction book "The Tiger: A True Story of Vengeance and Survival" from John Vaillant. It is set "on the Siberian plain, where human development is encroaching on the tigers' habitat -- and one tiger turns on the intruders." As the townspeople are tracked and hunted with an almost supernatural power, a conservationist game warden must fight back against the tiger.
The film is being put together as a project for Pitt to potentially star in.
"This is the first time I have adapted a screenplay, since I have previously only written original screenplays," stated Arriaga. "I chose to adapt this story, first, because I have a profound love for the outdoors and the intense tension between man and nature which the book reflects; and, second, because of the great privilege of working with such accomplished filmmakers as Darren Aronofsky, Brad Pitt, and James Schamus."
