It must be tough trying to have a little league baseball game when a zombified freak with a shotgun shows up in center field. (Then again, probably less dangerous than the concession hotdogs.) Opening this weekend, The Crazies is a remake of a George Romero movie from the 70s, and it’s your classic “happy small town goes freaking nuts from science gone awry” setup — in this, toxins in the water supply are to blame. (Reviews look pretty good; here’s the spooky trailer.) As it turns out, the movie was produced by the same folks who financed Al Gore’s An Inconvenient Truth, because they wanted a similar pro-environmental message to reach a bigger audience. Because nothing makes you worry about pollution more than the threat of toxic zombies trying to kill you.
