At the time, this was the highest-grossing film of Brad Pitt's career.

The Israeli Military Intelligence Directorate does indeed have a devil's advocate office to explore alternative assumptions and worst-case scenarios so intelligence assessments doesn't fall victim to "group think", but it is not called the 10th Man Doctrine.

Brad Pitt said of his involvement in the film - "This whole thing started because I just wanted to do a film that my boys could see before they turned 18 - one that they would like, anyways. And they love a zombie."

Max Brooks publicly stated that he felt the film had very little in common with his book beyond the central storyline.
