I recently re-watched this movie. I had forgotten how good it is. Unlike most zombie movies that tend to focus on a small, isolated group under threat. Typically, one or more of this group are mentally unhinged which adds to the suspense, but that set up has been a cliche for decades now.

WWZ takes the opposite approach. It takes the mile high view through the eyes of one scientist, who travels the globe trying to solve the dilemma.

The action pieces are imaginative and large scale. Interestingly, the final sequence is scaled right back down to the handful of isolated people for contrast.

It's interesting to read of all the behind-the-scenes troubles that plagued the making of this movie. In spite of it all, it all came together to create a very gritty and entertaining movie.

I would like to see a sequel to this movie. Pitt's character could put in an appearance, but it could be about a completely new group of people. This movie certainly left that possibility open, but it doesn't look like it's ever going to happen.
